matlab 2d plot with colors from 3rd variable

matlab 2d plot with colors from 3rd variable

ok, shame on me Yair, obviously it wasn’t the plot handle, might have been too late. @Kouichi – I believe that you are mistaken: Depending on exactly which type of Markers you have, it is possible that you simply need to modify the EdgeColorData instead of FaceColorData, and/or to modify EdgeColorType/FaceColorType from their default value of ‘truecolor’ to ‘truecoloralpha’. That would be very ideal. I have a nitpicky question: when I change any hidden property of my figures I have to manually select the line of code and execute it by itself (sometimes I have to repeat this twice before it works). h.FaceColorData * https://undocumentedmatlab.com/blog/bar-plot-customizations MATLAB Language Color-coded 2D line plots with color data in third dimension Example In MATLAB versions prior to R2014b , using the old HG1 graphics engine, it was not obvious how to create color coded 2D line plots . y: Array of values to use for the y-axis positions in the plot. My hunch is that the simpler markers are implemented as OpenGL primitives and these are not painted like the more complex markers and are therefore not as customizable. Matlab supports plotting multiple lines on single 2D plane. Related: https://undocumentedmatlab.com/blog/solving-a-matlab-hang-problem, Dear Yair, I get no transparency at all. You may receive emails, depending on your. Cool! ans = Clicking the Edit Plot icon will reset all markers. In general, painters does not render transparencies so in HG2 (R2014b onward) we need to use the slower opengl renderer for export. hLegendMarker = hLegendIconComponents.Children(1); GEOMS2 software supports scatterplot with a third variable for color (or bubble plot where third variable is size, or both of them with 4 variables). Mesh Plot. PS I found a workaround to save transparency changes in matlab 2015a: if you use saveas to save the file as *.svg, then open in Inkscape (free) and export as a png there, transparency values are saved. Choose a web site to get translated content where available and see local events and offers. You’ll probably still run into limitations with either of these though. Here's how one can use those colors in MATLAB. MaxFrameBufferSize: 0. EdgeColorBinding: 'object' As far as I can tell, changing the EdgeColorBinding (or FaceColorBinding) from ‘object’ to ‘interpolated’ or ‘discrete’ is problematic. hLegendIconComponents = hLegendComponents.Icon.Transform.Children; % child 1 = Marker, child 2 = LineStrip Have you discovered a similar issue and is there a workaround to this problem? As we can see, we can separately attach transparency values to the marker’s edges and/or faces. This tutorial is Automatically plot with different color lines. We will begin with a basic plot 3-D line plot. Although it doesn’t throw any error, it seems to ignore the settings in h(2).Face.ColorData(4). he.CapSize = 0; And, all the more convenient, it works when actual error-bars are needed. 140400 70.7850 1 140401 70.7923 2 140402 70.7993 3 140403 70.8067 4 140404 70.8139 5 140405 70.8212 3 Where the first column corresponds to time (one second intervals between data … I have been tasked with making a plot with a couple variables of available data. 3D. 0 114 189 255 while when the operation is successful, the class is: I have three variables (Return, Risk, Supply) where I would like to present them on a scatter plot as the attached. BR. Matlab can quite easily plot figures in 3D, so a 4D plot is a straightforward extension. EdgeColorData: [4x1 uint8] Until you use hold off or close the window, all plots appear in the … hey, i have many lines in X and Y axes, need to color each line according to a variable Z, how to do that ? I played with the rendering options, didn’t see any change or improvement! set(threednumeric3,'XDataSource','x_new3'); The mesh function creates a wireframe mesh. 4D plot - representing 3 variables function. It seems that when using plot3, if I have more than 25,000 points and I change my figure size or rotate the image, the MarkerHandle values revert back to the original settings and all color-information and/or transparency information is immediately reset. @Yair, I just saw your response. 210 215 220 225 230 235 240 245 250 255 Plot with color variation from third variable. * https://undocumentedmatlab.com/blog/customizing-histogram-plots, I tried using hBarChart.Face to change the colors of the bars, but it did not work. You can change their colors, marker size or any other properties by setting the quiver series properties . set(threednumeric3,'YDataSource','y_new3'); Hi, I used the suggested script on pc and worked fine. Carl, Cross-referenced solution (as for Fabian’s issue above, to add a call to drawnow): http://stackoverflow.com/a/35070679/233829, Yep, at least for me drawnow solved the problem. @Nasser – this is because you did not read carefully, and so you missed 3 important commands! So try using the ScreenCapture utility. Unable to complete the action because of changes made to the page. Perhaps the figure is not visible when it reaches that line of code, or maybe you just need to add a pause(0.1) and/or drawnow before your property-modification line. matlab: scatter plots with high number of datapoints. 3d plot colorscale xyz. Any hint into where to look for a begining of solution would be very welcome. hLine.MarkerFaceColor = [0.5,0.5,0.5]; Adding a pause in front of setting the alpha value makes it reliable again. MathWorks ist der führende Entwickler von Software für mathematische Berechnungen für Ingenieure und Wissenschaftler. hMarkers = hLine.MarkerHandle; Peter Rochford’s function which was an implementation of this didn’t work starting with r2018b anymore as he writes at the file exchange Then this works just fine. This example explores some of the ways to visualize high-dimensional data in MATLAB®, using Statistics and Machine Learning … EZ. Matlab Tutorial 1: Working with variables, arrays, and plotting Setting up Matlab First of all, let's make sure we all have the same layout of the different windows in Matlab. I find transparent markers really essential for making dense scatter plots readable. MaxTextureSize: 1024 Importantly, 2015b prints figures properly! yData = normrnd(1, 0.2, 1000, 1); Thanks so much, Yair. hMarkers.FaceColorData = uint8(255*[1;0;0;0.3]); % Alpha=0.3 => 70% transparent red. Invalid or deleted object. y . I’m using 2014b and I’ve tried exporting to png and pdf using both the painter and the OpenGL renderers with similar results. One possibility is essentially a 3D animation (time being the fourth variable). Or do I need to manually coded each PRN for each color? As far as I tested, the above is not true for R2016b. Array contains incorrect data values. hMarkers.FaceColorData = uint8(255*[1;0;0;0.3]); The dots are still the same color. barColor(n,4) = (6-n)*0.15; % each bar will have a different alpha But at least I can export my scatter plots now…. Hi Yair, Hi. Each specification can include characters for the line color, style, and marker. On the top, you will see a bar with your current folder. @Lukas – Matlab automatically removes transparency when you modify the axes (e.g., by rotation). 2d plot third variable. Vendor: 'Microsoft Corporation' Most likely cause is missing [] around left hand side that has a comma separated list expansion.“. VertexData: [3x10 single] : fake_y_error = zeros(length(data_y),1); an example of what I’m talking about can be found here: MarkerEdgeAlpha and MarkerFaceAlpha properties, as mentioned here. For example, if I set x = [1:10] and y = [1:10], and I plot(x,y,’o’), is it possible to change the circles to triangles from x(2:4)? My z-variable is also a 1xn vector. You should learn to navigate MATLAB's documentation, then … I don't know however how i can plot the 3rd variable… 'LineWidth' , 0.25 ); I built a bunch of pretty figures with this but they are stuck within Matlab 🙁. Software: 'true' I've succeeded in writing a file that plots the points where measurements were done on the already existing map. he_mh = he.MarkerHandle; I've succeeded in writing a file that plots the points where measurements were done on the already existing map. Specify the colors for a surface plot by including a fourth matrix input, CO.The surface plot uses Z for height and CO for color. The comment of Arnold there is weird though. In other words what would be the equivalent for MarkerHandler in a bar chart? I would like to plot them based on the two variables (Return and Risk) and I would like to color them based on the third variable (supply). This website uses cookies to improve your user experience, personalize content and ads, and analyze website traffic. I would like to know how to make matplotlib’s scatter function colour points by a third variable. Return the chart line in the output variable p. t = linspace(-10,10,1000); xt = exp(-t./10). I’d love to set these to a vector. However, when I moved to mac the same script stop working, and I have not transparency gradient. No way to make transparent marker faces / edges on a 3D plot? It works for me… Perhaps you are using software emulation (not hardware acceleration) in your opengl. 2D Plots in Matlab is a feature that enables a user to create the two-dimensional graph for any dependent variable as a function of a depending variable. pl = plot(x,y,'*'); the problem is once exporting either using saveas or print functions, the transparency is not saved and gives a full normal color image! 98 1 1 gold badge 2 2 silver badges 8 8 bronze badges. or any way to export the figure exactly as it’s shown in the Figure window? @EZ – transparency output is (and always was) problematic in Matlab. Learn more about color coded, imagesc, plotting, custom color grid, heatmap @Claire – it should work in a script/function as well. I have been using the keepAlpha trick with success as well to keep transparency on the figure Markers when toggling the legend. I use 2014b on Win8. I was the OP for that SO question, btw 🙂. If you have a cell array of (unique) labels, and an N x 3 RGB array of corresponding color specifications, then the easiest way would be to sort() the (unique) label names and pull out the sorting order (second output of sort()) and use that order to rearrange the color table rows to create the cmap variable above, and also use the order to re-arrange the legends. Any idea on that? @Pierre – thanks for sharing this clever useful trick, IB-Matlab: InteractiveBrokers-Matlab connector, EODML: EODHistoricalData-Matlab connector, While setting the 'MarkerFaceColor' property of Line: It allows you to create a scatter plot using the value of a 3rd variable to set the color of you points. 2D plot by including third parameter as colorbar. Here are the full code lines that I used: CMtrans=uint8(255*(sum(hint.mat_norm(markersIn,:),1)./max(sum(hint.mat_norm(markersIn,:),1)))); age of people). I will try a 2016 release on another computer tomorrow. Version: '1.1.0' ha = plot(xData, yData, 'ko'); They really open up a plethora of charting options that come in very handy, in my case. Try using print -dpdf and/or the export_fig utility. Next time please be more considerate of others. Visual: 'Visual 0x0e, (RGB 24 bits (8 8 8), Z ...' Take A Sneak Peak At The Movies Coming Out This Week (8/12) Weekend Movie Releases – January 15th – January 17th hMarkers.get It creates a line plot for data ‘Y’ with respect to its corresponding data in the … plot3. >> hMarkers.EdgeColorData.get %This can neither. How to make 3D mesh plot in matlab with three diffrent variables? z=1 ... %You can choose other values and see the difference surfl(z); % surface plot with color-based lighting. Learn more about plot between a matrix, a vector and another matrix Visible: 'on' SupportsAlignVertexCenters: 0 drawnow; >> hMarkers.FaceColorData' % 4-element uint8 array drawnow Absolutely terrific! 2D colour coded plot with already binned data . PickableParts: 'visible' Reload the page to see its updated state. Thanks for you reply. hm.FaceColorData = cFace; EdgeColorType: 'truecolor' Thanks a lot. he_mh.FaceColorType = 'truecoloralpha'; I was wondering if you have had any success in using other renderers? … Entering Edit Plot mode (the pointer icon on the toolbar) resets the ColorBinding and ColorData back to ‘object’ and the original color. the scatter plot was prepared for part of the full cell number! Stairs Plot. By default, the color of the mesh is proportional to the surface height. For example: line(1:10, 1:10, 'LineStyle','-'); % original line with no markers 'MarkerFaceColor', [0 114 189]/255, ... set([h.Face], 'ColorType', 'truecoloralpha') From colors to shading and lighting, the only tools needed are MATLAB and your know-how. However, this works for me just with the filled (heavier) markers like ‘o’, not for the lighter markers like ‘.’ and ‘+’. Starting in R2019b, you can display a tiling of plots using the tiledlayout and nexttile functions. Many statistical analyses involve only two variables: a predictor variable and a response variable. fbarHandle = bar( ax_fBar , ... Then I tried a tight loop, plotting a single point at a time (doing this to assign a different color to each point in the graph), and invariably within a few loop cycles, when I grab the “plothandle.MarkerHandle”, it’s empty. Thank you so much for this page, it is fantastic! I do not get any errors, but colors do not change. Is that the case? 'MarkerEdgeColor', [0 114 189]/255, ... Warning: Error creating or updating Marker hMarkers = threednumeric3.MarkerHandle; % a matlab.graphics.primitive.world.Marker object (sorry about directly emailing – I missed your warnings) x=1:10; y=10*x; hLine=plot(x,y,'o-'); drawnow; set(hMarkers,'FaceColorBinding','interpolated', 'FaceColorData',CMdata); solved. For example, I am wondering about how to use the xxBinding properties; how exactly do ‘object’, ‘interpolated’, ‘discrete’ and ‘none’ work? I am facing problems exporting such figures as a pdf/svg to modify it using illustrator, especially when I have multiple subplots! @Fabian – simply add a drawnow call after your plot(), before accessing hLine.MarkerHandle. You can use c to specify a variable to use for the color values and you can use cmap to specify the actual colors to use for the markers in the scatterplot. Can someone help me ? I could have done so by passing 3rd variable to the color palette, but this would disrupt the relationship information among them. *sin(5*t); yt = exp(-t./10). hLegendComponents = hLegend.EntryContainer.Children; % hLegendComponents has 2 children: child 1 = LegendIcon, child 2 = Text (label) >> set(hMarkers,'FaceColorBinding','interpolated', 'FaceColorData',colorData). Of course it still works. Active 1 year, 2 months ago. Layer: 'middle' There is also the possibility that this is due to your use of OpenGL emulation mode (software=’true’). Facebook. It used to be that zbuffer would do the trick (loses vector format) but at least the transparency property is not lost. hMarkers.FaceColorType = 'truecoloralpha'; On the screen, I have a nice figure, but once exporting the figure I am loosing all. It turns out nicely! Still, have the same problem. *cos(5*t); p = plot3(xt,yt,t); Change the line width to 3. p.LineWidth = 3; Specify Target Axes. 'BarWidth' , 0.8 , ... Thanks so much, adding the drawnow did the trick! newcolordata(:,1) = [255;0;0;255]; % Turn the first marker red This is again one of the MATLAB 2D plots that look more like stairs. Thanks. @Marconi – this has already been reported by others on this blog. shading interp colormap colorcube. By continuing to use this website, you consent to our use of cookies. Many thanks for this post. barColor = repelem([0.5, 0.5, 0.5], 5, 1); % all 5 bars will have the same color Accelerating the pace of engineering and science. I tried this with R2016b and ran into similar issues when trying to export, i.e. Thanks again. Change color of 2D plot line depending on 3rd value. Call the tiledlayout function to create a 2-by-1 tiled chart layout. Now I would like to specify that the curves are displayed with different colors with respect to the value of a used random variable. @Hassan – check perhaps a different figure renderer is used on your two computers. hm.EdgeColorData = cEdge; hMarkers = hLine.MarkerHandle; The official color for Loyola Green is given as RGB:0-104-87, and Loyola Gray is given as RGB:200-200-200 (found on Loyola's Logos/University Signature page. hMarkers = L2.MarkerHandle; I have been tasked with making a plot with a couple variables of available data. @(ObjH, EventData) keepAlpha(ObjH, EventData, cFace, cEdge)); function keepAlpha(src,eventData, FaceColor, EdgeColor) Learn more about scatter, 2d plot, color Your post solves this 🙂 Here are the RGB triplets and hexadecimal color codes for the default colors MATLAB uses in many types of plots. In >2014, zbuffer is no longer an option. . hm = ha.MarkerHandle; Thanks for writing this post. Thanks for this awesome post. ans = As Paul has noted in a comment last week, we cannot simply set a 4th (alpha transparency) element to the MarkerFaceColor and MarkerEdgeColor properties: >> hMarkers = hLine.MarkerHandle; % a matlab.graphics.primitive.world.Marker object addlistener(ha,'MarkedClean',... Or at least I’ve figured out how to avoid it. Or do I have to use the patch command? Sign in to comment. When I use plot function, the transparency settings are always reset by any command related to the current figure. This example shows how to create a variety of 3-D plots in MATLAB®. To make life easier, all files you save and … My goal is to plot two variables, and vary the color of the lines by the third variable. Use quiver to plot vector arrows on a 2D plot, or quiver3 to plot arrows in a 3D plot. I had another look and of course you’re right, it works. I'm to make a normal 2D scatter plot of the data with respect to 2 of the variables given, easy enough. h = area(magic(4)); drawnow; % 1x4 area object hm.EdgeColorData = EdgeColor; %This cannot show the current value of the markers. . Did I ever say “h.FaceColorData” (where h is the plot return handle) anywhere in my post? 128 128 128 255. The lines for data Y1, Y2,…,Yn with respect to their … Questions gnuplot linecolor variable in matplotlib? @DaV – I suspect that you have some extra code between the line where you plot() the data and the line where you extract/update the hMarkers and in the meantime either the line or the markers were deleted. 2D scatter plot with Z-value in color. However, many datasets involve a larger number of variables, making direct visualization more difficult. hm.FaceColorData = FaceColor; I was not aware of SizeData… MATLAB: How to plot 3D data on 2D coordinate system with 3rd item indicated by color scale. Thanks. I wondered a bit as there were actually nothing different between the code and what I tried yesterday but the last line. You can use a screen capture utility to capture the actual appearance and then print from that screen-capture. We will begin with a basic plot 3-D line plot. FaceColorData: [4x1 uint8] A few examples of how to use these functions are included in the download and there is also a Wiki on GitHub. http://glowingpython.blogspot.co.at/2011/11/how-to-make-bubble-charts-with.html. I am getting a warning message after running the following command, hMarkers.FaceColorData=CMdata; hmarkers = pl.MarkerHandle; FaceColorBinding: 'object' drawnow >> hMarkers = hLine.MarkerHandle; My x and y are both 1xn vectors (n is something like 5000 for example). Yup, that works. y=10*x; Let’s add more flavor to it. Hello, h = area(magic(4)); drawnow; % 1x4 area object drawnow Hello, I successfully applied the transparency and color gradient to the markers. I want to change size of Brushing marker. I need to plot a color codded 2d graph between 1st and 2nd variable and color has to put as height of 3rd variable. LinkedIn. The below MATLAB code is designed to generate plots for two functions pt, qt with the common depending variable t with the single call of the method fplot(). A colormap is an m-by-3 matrix of real numbers between 0.0 and 1.0. Any help? My code looked something like this: scatter(X, Y, 6, 'filled', ... I found an issue, though I don’t think it’s related to this method “per se”. E.g. I am trying to plot with variable x with respect to another y and add a colormap based on the values of another variable z So the plot should be similar … I found that when I upgraded to Matlab 2016a, the transparency functions will generate figures in the correct way but will not print the transparencies. % ! shading interp colormap colorcube. hMarkers.get % hence this does nothing 4. , n and then join them by straight lines. I have written a collection of Matlab functions for creating semi-transparent markers in plots and legends. Is there a way to fix that? The default standard function for 2D graph plotting is plot() function. asked Aug 14 '12 at 17:39. user1598764 user1598764. Whenever this command is called the previous settings are discarded and all areas have the same color and no transparency. 6. An eye-opener 🙂. Even without changing EdgeColorBinding/FaceColorBinding from ‘object’ to ‘interpolated’ or ‘discrete’, the original color is reset back to the original color if a legend is added to the plot: x=1:10; I have a data set that looks like this. Am I missing something? The Matlab version I’m using is R2019a. Not able to find any documentation on this. To add plots to an existing figure, use hold on. h(2).Face.ColorData(4) = 90; % =90/255=35% opaque =65% transparent I copy/paste your sample and run it. Learn more about scatter, 2d plot, color RGB Triplet Hexadecimal Color Code Appearance [0 0.4470 0.7410] '#0072BD' [0.8500 0.3250 0.0980] '#D95319' [0.9290 0.6940 0.1250] '#EDB120' [0.4940 0.1840 0.5560] '#7E2F8E' [0.4660 0.6740 0.1880] '#77AC30' [0.3010 0.7450 0.9330] '#4DBEEE' [0.6350 … I would like to plot them based on the two variables (Return and Risk) and I would like to color them based on the third variable (supply). We also chose to move the legend in the area of extrapolation. he_mh.FaceColorData = uint8(255*[1;0;0;0.3]); >> ver Thanks for any help. s: The marker size. (refer code) and resulting as photo below. 3d plot colorscale xyz. @Tyler – you cannot do that on the plotted markers directly, but you could create the line with no markers, and then overlay it with 2 additional lines that have no line, just the markers. Ask Question Asked 5 years, 5 months ago. At the beginning of each Matlab session, it is important to select your working folder. The basic MATLAB graphing procedure, for example in 2D, is to take a vector of x coordinates, x = (x1, . @Yair – Ah, I’ve figured out my problem. However, the color input has to be a matrix. Thanks again for your kind help and for putting this down for others to read! Assuming you used the builtin area function to generate the plot, you can set the FaceAlpha property of the area-plot’s children. number of people). Color value must be a 3 element numeric vector, % a matlab.graphics.primitive.world.Marker object, % Otherwise pl.MarkerHandle gives me GraphicsPlaceholder objects. >> hMarkers = hLine.MarkerHandle; Hi all; It’s the same as 2-D plot with addition of 3rd vector (array). Looks really neat. Contour plot with contour lines colored using a continuous outcome variable (qsec) Instead of coloring the whole plot, it may be more desirable to color just the contour lines of the plot. @Pawel – you have a bug in your code. hMarkers = hLine.MarkerHandle; % a matlab.graphics.primitive.world.Marker object A major benefit of this package is that it enables the user to have the semi-transparent markers also appear in the legend. When I try to export the figure, the transparency of the markers is lost, but the transparency of other objects is kept (for example, patches). The above does not work on Matlab 2016a. At least in 2014b. I finally have my transparent scatter plots back in 2015a! I've succeeded in writing a file that plots the points where measurements were done on the already existing map. I really liked this hidden feature, but as far as I can see, R2017a and R2017b (prerelease) do not support the alpha setting of Markers as in: hMarkers.FaceColorData = uint8(255*[1;0;0;0.3]); The markers turn red by this, but they are not transparent. 200 190 180 170 160 150 140 130 120 110 Then export_fig works its magic and everything looks great (even in pdf!). MATLAB: 2D plot with 3rd variable. Can you confirm that using e.g. So you can use 1/255[255,0,0] to get the color of red to use as a color in MATLAB. Starting in R2019b, you can display a tiling of plots using the tiledlayout and nexttile functions. Do you have any suggestion for this situation? Note that it only generates bitmap sceenshots, not vectorized (PDF/EPS) ones. . barColor = uint8(barColor); What is the proper way to manage this? In this case, try it with a newer release if you can. I’m still finding my way around MATLAB, and unfortunately I’m stuck – was wondering if I can access the hidden MarkerHandle in Matlab 2013a? MATLAB. Operating System: Microsoft Windows 7 Home Premium Version 6.1 (Build 7601: Service Pack 1) One more question: in MATLAB, I frequently need to generate a 2D scatter plot with: (1) use individual marker transparencies to encode a 3rd variable (e.g. Yes of course. >> hMarkers.EdgeColorData = [1,1,1,0.2]; MATLAB plots play an essential role in the field of mathematics, science, engineering, technology, and finance for statistics and data analysis. The official color for Loyola Green is given as RGB:0-104-87, and Loyola Gray is given as RGB:200-200-200 (found on Loyola's Logos/University Signature page. I have corresponding Z values for X and Y coordinates . and retaining the transparency. It's also possible to visualize trivariate data with 3D scatter plots, or 2D scatter plots with a third variable encoded with, for example color. % keep transparent So, I have been using errorbar instead of plot, with a ‘fake’ error vector, and a capsize equal to 0. This post has been really useful to me. HitTest: 'off' The following code snippet should work as-is: hLine = plot(1:5,2:6,'o','LineWidth',2); drawnow; I have three variables (Return, Risk, Supply) where I would like to present them on a scatter plot as the attached. Any idea why that is? I’m stuck here: I do not know of any possibility to vary the marker sizes individually. Do you have any idea or suggestion? However, when I use errorbar the transparency settings are kept. Oh, sorry, PlotTbl does not allow the precise control of colors that you want. I find it very annoying that even copying some tutorial lines into my matlab doesn’t help set the target transparent. h(2).Face.ColorData(4) = 90; % =90/255=35% opaque =65% transparent. class 'matlab.graphics.chart.primitive.Line'. Creating simple plots. I’ve also noticed that none of the changes made using MarkerHandle are reflected by the line properties. Is there a new way? It seems that if you set LineStyle, Marker, MarkerSize, or any items of that nature using the line handle before using hLine.MarkerHandle, then MarkerHandle becomes inaccessible. cFace = uint8(255*[0 0 1 0.1])'; number of people). Error in value of property ColorData In order to customize the legend itself, we need to dig into the legend object’s hierarchy. cEdge = uint8(255*[0 0 0 0.3])'; It seems that you need to set FaceColorType/EdgeColorType to ‘truecoloralpha’ in order to get transparency effect. Syntax: stairs(x,y) stairs(x,y,'colourmarkerlinspec') MATLAB Code: Here, I am writing the MATLAB code of stairs plot with the black (k) color … line(2:4, 2:4, 'LineStyle','none', 'marker','^', 'MarkerFaceColor','g'); % green triangle markers. he = errorbar(x_data, y_data, fake_y_error) Thanks a lot for the trouble shooting.
