# matlab 2d plot with colors from 3rd variable

shading interp colormap colorcube. Plotting is a graphical representation of a data set that shows a relationship between two or more variables. @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. Java Version: Java 1.7.0_60-b19 with Oracle Corporation Java HotSpot(TM) 64-Bit Server VM mixed mode. Sweet. For example, is there a hidden way to access the handles to the Markers that are in the legend ? >> hMarkers = hLine.MarkerHandle; fbarHandle = bar( ax_fBar , ... xData = normrnd(1, 0.2, 1000, 1); I’ve been looking into hidden lines, axes properties, but I can’t find it anywhere. In order to customize the legend itself, we need to dig into the legend object’s hierarchy. hm.FaceColorData = FaceColor; In >2014, zbuffer is no longer an option. The extra pause() (or drawnow) call forces Matlab’s graphic engine to flush (execute) any pending graphic rendering events in its graphics queue, thereby ensuring that when you set the transparency it “sticks”. For example, subplot and color/symbol selection: In [7]: subplot(1,2,1) plot(x, y, 'r--') subplot(1,2,2) plot(y, x, 'g*-'); The good thing about the pylab MATLAB-style API is that it is easy to get started with if you are familiar with MATLAB, and it has a minumum of hMarkers = hLine.MarkerHandle; . rng(144); I finally have my transparent scatter plots back in 2015a! You will then see the transparent markers nicely. I’ve also noticed that none of the changes made using MarkerHandle are reflected by the line properties. . It’s the same as 2-D plot with addition of 3rd vector (array). As far as I can tell, changing the EdgeColorBinding (or FaceColorBinding) from ‘object’ to ‘interpolated’ or ‘discrete’ is problematic. z=1 ... %You can choose other values and see the difference surfl(z); % surface plot with color-based lighting. Renderer: 'GDI Generic' the scatter plot was prepared for part of the full cell number! hMarkers = hLine.MarkerHandle; an example of what I’m talking about can be found here: drawnow; % Otherwise pl.MarkerHandle gives me GraphicsPlaceholder objects … h(2).Face.ColorData(4) = 90; % =90/255=35% opaque =65% transparent ha = plot(xData, yData, 'ko'); As we can see, we can separately attach transparency values to the marker’s edges and/or faces. We also chose to move the legend in the area of extrapolation. MarkerEdgeAlpha and MarkerFaceAlpha properties, as mentioned here. Active 1 year, 2 months ago. h = area(magic(4)); drawnow; % 1x4 area object Do you have any suggestion for this situation? Read the post text carefully and try the code snippets one by one. hMarkers.FaceColorData = uint8(255*[1;0;0;0.3]); % Alpha=0.3 => 70% transparent red. Hope this will help others as well. It will not just execute itself if I run it as a script or a function. 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 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). 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. y=10*x; hMarkers.FaceColorData = uint8(255*[1;0;0;0.3]); Hi! Thank you kindly. I have written a collection of Matlab functions for creating semi-transparent markers in plots and legends. age of people). Thanks, this is useful — setting an alpha component is a better way to visualise density than applying jitter. I have a data set that looks like this. There are several functions available in MATLAB to create 2-dimensional and 3-dimensional plots. But at least I can export my scatter plots now…. hMarkers.FaceColorData=CMdata; In this case, try it with a newer release if you can. Thanks. Any idea why that is? FaceHandle = get(fbarHandle.Face); While there are appropriate object properties (Size for the Line class, and MarkerSize for the MarkerHandle class), these are apparently required to be scalars. This example shows how to create a variety of 3-D plots in MATLAB®. Did I ever say “h.FaceColorData” (where h is the plot return handle) anywhere in my post? @Yair – Ah, I’ve figured out my problem. he_mh.FaceColorType = 'truecoloralpha'; You are probably doing something wrong. I’m using 2014b and I’ve tried exporting to png and pdf using both the painter and the OpenGL renderers with similar results. Hi all; hm.EdgeColorData = cEdge; x . Any idea what’s going wrong? For example: line(1:10, 1:10, 'LineStyle','-'); % original line with no markers hLegendComponents = hLegend.EntryContainer.Children; % hLegendComponents has 2 children: child 1 = LegendIcon, child 2 = Text (label) Call the nexttile function to create an axes object and return the object as ax1.Create the top plot by passing ax1 to the plot function. We will begin with a basic plot 3-D line plot. h = area(magic(4)); drawnow; % 1x4 area object 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. I copy/paste your sample and run it. @Fabian – simply add a drawnow call after your plot(), before accessing hLine.MarkerHandle. I did some further tests and I think I found at least one problem. hmarkers = pl.MarkerHandle; Thanks so much, Yair. One more question: in MATLAB, I frequently need to generate a 2D scatter plot with: 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. E.g. Cool! VertexIndices: [] >> hMarkers = hLine.MarkerHandle; Vendor: 'Microsoft Corporation' But it is not working now! @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’. I tried this with R2016b and ran into similar issues when trying to export, i.e. MATLAB License Number: STUDENT 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 In general, painters does not render transparencies so in HG2 (R2014b onward) we need to use the slower opengl renderer for export. https://www.mathworks.com/matlabcentral/fileexchange/65194-peterrochford-markertransparency. Using MATLAB for this purpose allows you to have complete control over the customization of your graph. How to make 3D mesh plot in matlab with three diffrent variables? Is that the case? FaceColorData: [4x1 uint8] % keep transparent With the help of MATLAB (Matrix Laboratory), you'll be able to create stunning 3-D visuals with the data you provide. Try using print -dpdf and/or the export_fig utility. When I run the area command within a loop for plotting multiple sets of data into one plot it sometimes happens that the x-axis is resized to fit the data. Without the pause/drawnow, the graphics queue might reset the transparency after you have set it, depending on internal timings over which we have no control. Find the treasures in MATLAB Central and discover how the community can help you! This can be achieved by using the stat_contour aesthetic over the scale_fill_manual aesthetic. Of course it still works. hMarkers = threednumeric3.MarkerHandle; % a matlab.graphics.primitive.world.Marker object addlistener(ha,'MarkedClean',... 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. >> hMarkers.EdgeColorData = [1,1,1,0.2]; As far as I tested, the above is not true for R2016b. I am facing problems exporting such figures as a pdf/svg to modify it using illustrator, especially when I have multiple subplots! Thanks so much, adding the drawnow did the trick! 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. It would be nice if you would cite a reference to this page in the File Exchange description text, and in your GitHub README.md file. set(threednumeric3,'YDataSource','y_new3'); https://de.mathworks.com/matlabcentral/answers/711563-plot-with-color-variation-from-third-variable#answer_593428, https://de.mathworks.com/matlabcentral/answers/711563-plot-with-color-variation-from-third-variable#comment_1251453. However, when I moved to mac the same script stop working, and I have not transparency gradient. Hey Guys, I've been trying to make a map which has indicators for the velocity that has been measured. Nothing changed. Is there also a hidden MarkerHandle or something similar for animatedline? Hi all. It used to be that zbuffer would do the trick (loses vector format) but at least the transparency property is not lost. LineWidth: 0.5 Learn more about plot, 2d, third variable FaceColorBinding: 'object' % plot and make transparent The basic MATLAB graphing procedure, for example in 2D, is to take a vector of x coordinates, x = (x1, . threednumeric3=scatter3(x_new3,y_new3,z_new3,'blue') hm = ha.MarkerHandle; Cheers. @Grunde – Yes this is possible, but I don’t think you need to use any undocumented features for this. 'MarkerFaceAlpha', 0.1); “Throughout today, weâve kept the default FaceColorType/EdgeColorType value of ‘truecolor’ (which is really the same as ‘truecoloralpha’ as far as I can tell, since both accept an alpha transparency value as the 4th color element).”. I don't know however how i can plot the 3rd variable… >> hMarkers.get Invalid or deleted object. Error in value of property ColorData FaceHandle.ColorBinding = 'interpolated'; Alternatively, you can use the builtin alpha function. Thanks for any help. Hi Yair, Now I would like to specify that the curves are displayed with different colors with respect to the value of a used random variable. , n and then join them by straight lines. Now I want to keep the color varying and I would like to make any value of the supply that is higher than 4800 blue and … You should really try to update your graphics driver so that Matlab will use OpenGL hardware acceleration (software=’false’), because the new graphics engine relies on OpenGL hardware much more than the previous graphics system (HG1, used until R2014a). Take A Sneak Peak At The Movies Coming Out This Week (8/12) Weekend Movie Releases – January 15th – January 17th Oh, sorry, PlotTbl does not allow the precise control of colors that you want. Software: 'true' Hi, I have three related variables (vectors) and would like to see their distribution on a 2D plot of first two variables, having colors proportional to the values from third variable. However, this works for me just with the filled (heavier) markers like ‘o’, not for the lighter markers like ‘.’ and ‘+’. Specify the colors using truecolor, which uses triplets of numbers to stand for all possible colors.When you use truecolor, if Z is m-by-n, then CO is m-by-n-by-3.The first page of the array indicates the red component for each color, the second page indicates … Until you use hold off or close the window, all plots appear in the … I found an issue, though I don’t think it’s related to this method “per se”. Hello, It will print transparencies correctly. 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). I found that MATLAB’s scatter command does pretty much exactly what I wanted by setting the (mildly undocumented?) L2=scatter(ax,hint.xy(cellsIn,1),hint.xy(cellsIn,2),floor(ms2*frac),mCol,'filled'); z = peaks(25); figure mesh(z) Surface Plot. Creating Plotting. Learn more about color coded, imagesc, plotting, custom color grid, heatmap 6. A few examples of how to use these functions are included in the download and there is also a Wiki on GitHub. end or any way to export the figure exactly as it’s shown in the Figure window? Hi Dani and Yair, Use MATLAB2015b! The comment of Arnold there is weird though. How to design the stairs plot in MATLAB? Any idea what’s going on? plot3. hMarkers.FaceColorData = uint8(255*[1;0;0;0.3]); % Alpha=0.3 => 70% transparent red - restored after the legend call 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. Visible: 'on' export_fig is exporting the figure without applying the transparency to the markers. 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). Thanks. Most likely cause is missing [] around left hand side that has a comma separated list expansion.“. drawnow The mesh function creates a wireframe mesh. I’m stuck here: I do not know of any possibility to vary the marker sizes individually. 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 … MATLAB. EZ. In other words what would be the equivalent for MarkerHandler in a bar chart? Size: 6 I built a bunch of pretty figures with this but they are stuck within Matlab ð. Thanks for you reply. But when I try to print, Matlab2014b clears everything. 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 … z=1 ... %You can choose other values and see the difference surfl(z); % surface plot with color-based lighting. Thank you for this post, it is very useful. 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. Adding a pause in front of setting the alpha value makes it reliable again. Extensions: {3x1 cell} Reload the page to see its updated state. My x and y are both 1xn vectors (n is something like 5000 for example). This is not too difficult: hLegend = legend('on'); plot-lines with transparency and color gradient, Plot line transparency and color gradient, http://glowingpython.blogspot.co.at/2011/11/how-to-make-bubble-charts-with.html, https://undocumentedmatlab.com/blog/hg2-update#testing, http://stackoverflow.com/a/35070679/233829, https://undocumentedmatlab.com/blog/bar-plot-customizations, https://undocumentedmatlab.com/blog/customizing-histogram-plots, https://www.mathworks.com/matlabcentral/fileexchange/65194-peterrochford-markertransparency, https://undocumentedmatlab.com/blog/solving-a-matlab-hang-problem, Speeding-up builtin Matlab functions â part 3, Matlab toolstrip â part 9 (popup figures), Matlab toolstrip â part 7 (selection controls), Matlab toolstrip â part 6 (complex controls), Matlab toolstrip â part 4 (control customization), Reverting axes controls in figure toolbar, Matlab toolstrip â part 3 (basic customization), Matlab toolstrip â part 2 (ToolGroup App), Medium risk of breaking in future versions, Matthias Brenneis (101 days 20 hours ago). Accelerating the pace of engineering and science. @Yair, I just saw your response. Based on your location, we recommend that you select: . I do not get any errors, but colors do not change. barColor = uint8(barColor); 3d plot colorscale xyz. Here are the RGB triplets and hexadecimal color codes for the default colors MATLAB uses in many types of plots. 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 . the transparency would be lost. MATLAB: How to plot 3D data on 2D coordinate system with 3rd item indicated by color scale. BR. Learn more about scatter, 2d plot, color %_______________Read data_______________%, %>>>>>>>>>>>>>>>>>>>>>>>>>>>>> FIGURE starts. for n = 1:5 (2) use individual marker sizes to encode a 4th variable (e.g. set(hMarkers,'FaceColorBinding','interpolated', 'FaceColorData',CMdata); solved. barColor(n,4) = (6-n)*0.15; % each bar will have a different alpha The area object doesn’t have any children. drawnow A plot can present the data in continuous, discrete, surface or volume form. “matlab.graphics.primitive.world.Marker”, I’ve tried things like clearing variables every loop, putting in a delay timer, and so on, with no luck. 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. A major benefit of this package is that it enables the user to have the semi-transparent markers also appear in the legend. 98 1 1 gold badge 2 2 silver badges 8 8 bronze badges. 4D plot - representing 3 variables function. @Antonius – the corresponding internal objects in a bar chart are hBarChart.Edge and hBarChart.Face. I have the following code that worked for me in the past. Yup, that works. @Marconi – this has already been reported by others on this blog. Invalid or deleted object. Not able to find any documentation on this. I will try a 2016 release on another computer tomorrow. 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(). Thanks a lot for the very useful hack. * https://undocumentedmatlab.com/blog/bar-plot-customizations hLegendMarker = hLegendIconComponents.Children(1); %This cannot show the current value of the markers. hMarkers = L2.MarkerHandle; Newsletter sign up. Still, have the same problem. 'BarWidth' , 0.8 , ... Starting in R2019b, you can display a tiling of plots using the tiledlayout and nexttile functions. This will reset back the original color. % ! Is there a new way? EdgeColorType: 'truecolor' : fake_y_error = zeros(length(data_y),1); Such data are easy to visualize using 2D scatter plots, bivariate histograms, boxplots, etc. 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)? Note that this discussion (like the preceding several posts) deal exclusively with HG2, Matlab’s new graphics system starting with R2014b (well yes, we can also turn HG2 on in earlier releases). while when the operation is successful, the class is: Learn more about scatter, 2d plot, color I don't know however how i can plot the 3rd variable, the velocity, on there as well. ok, shame on me Yair, obviously it wasn’t the plot handle, might have been too late. I’m trying this in matlab r2015a, I got the same problem as Fabian, but the drawnow command does not solve the problem. c: Array of values to use for marker colors. Thank you for the terrific post! From colors to shading and lighting, the only tools needed are MATLAB and your know-how. ans = 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. I created events listeners for markers in both plot and legends. line([1,5:9], [1,5:9], 'LineStyle','none', 'marker','o', 'MarkerFaceColor','r'); % red circle markers No appropriate method, property, or field 'FaceColorData' for cFace = uint8(255*[0 0 1 0.1])'; Hi, I used the suggested script on pc and worked fine. Plot with color variation from third variable. To make life easier, all files you save and … The following code snippet should work as-is: hLine = plot(1:5,2:6,'o','LineWidth',2); drawnow; 2D plot by including third parameter as colorbar. Or do I have to use the patch command? Sign in to comment. This tutorial is Automatically plot with different color lines. This website uses cookies to improve your user experience, personalize content and ads, and analyze website traffic. 2D scatter plot with Z-value in color. hLine.MarkerFaceColor = [0.5,0.5,0.5]; and retaining the transparency. I've succeeded in writing a file that plots the points where measurements were done on the already existing map. Reddit. Thanks for this awesome post. Hi – re your column on assigning transparency to plot markers: I tried the code on a simple example and all was well. hMarkers.FaceColorData = uint8(255*[1;0;0;0.3]); % Alpha=0.3 => 70% transparent red Unable to complete the action because of changes made to the page. However, when I run your code (see below), hMarkers is empty. I have nothing new except or using different dataset (the Matlab version is the same 2016a). CMdata=uint8([repmat(mCol'*255,1,length(CMtrans)); CMtrans]); I've done this before using scatter easily with the following code: I've done this before using scatter easily with the following code: Clicking the Edit Plot icon will reset all markers. MATLAB Version: 9.0.0.341360 (R2016a) xlim([1.5 2.5]), So, finally I figured it out how to circumvent the problem with the resizing. @(ObjH, EventData) keepAlpha(ObjH, EventData, cFace, cEdge)); function keepAlpha(src,eventData, FaceColor, EdgeColor) . It seems like there is no MarkerHandle object created when using plot3. Even without changing EdgeColorBinding/FaceColorBinding from âobjectâ to âinterpolatedâ or âdiscreteâ, the original color is reset back to the original color if a legend is added to the plot: x=1:10; Your post solves this (2) use individual marker sizes to encode a 4th variable (e.g. Many thanks in advance. 2D plot with 3rd variable. Type opengl(‘info’) to find out. You may receive emails, depending on your. It seems that you need to set FaceColorType/EdgeColorType to ‘truecoloralpha’ in order to get transparency effect. Is it possible to make the area plots transparent? You’ll probably still run into limitations with either of these though. Would the optimal solution be to create a function myLegend that would design the legend from scratch ? @Priyanka – this functionality is only available in Matlab’s new graphics system (HG2), which became officially available in Matlab release R2014b (i.e., 3 releases after yours). That works fine to rebuild after a click in ‘show plot tools’; but won’t work in print preview… ð. 3d plot colorscale xyz. Note that it only generates bitmap sceenshots, not vectorized (PDF/EPS) ones. Stairs Plot. . 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 don't know however how i can plot the 3rd variable… Each specification can include characters for the line color, style, and marker. @Hassan – check perhaps a different figure renderer is used on your two computers. he_mh = he.MarkerHandle; Very strange. It’s a pretty awful hack job to achieve what I feel should be basic functionality but here we go: % generate data Hey Guys, I've been trying to make a map which has indicators for the velocity that has been measured. 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. . 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. I have a question on printing figure to pdf (or any format really!) Then export_fig works its magic and everything looks great (even in pdf!). The surf function is used to create a 3-D surface plot. EdgeColorBinding: 'object' Short Example: x = 1:10; y= 1:10; For example, I am wondering about how to use the xxBinding properties; how exactly do ‘object’, ‘interpolated’, ‘discrete’ and ‘none’ work? Sign in to answer this question. Twitter. 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. hMarkers.FaceColorType = 'truecoloralpha'; hMarkers.FaceColorType = 'truecoloralpha'; 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 … , yN ), locate the points (xi , yi), with i = 1, 2, . It’s the same as 2-D plot with addition of 3rd vector (array). cEdge = uint8(255*[0 0 0 0.3])'; Here's how one can use those colors in MATLAB. (1) use individual marker transparencies to encode a 3rd variable (e.g. *sin(5*t); yt = exp(-t./10). Thanks a lot. I was wondering if you have had any success in using other renderers? You should learn to navigate MATLAB's documentation, then … This is again one of the MATLAB 2D plots that look more like stairs. 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? We will begin with a basic plot 3-D line plot.
