matlab 2d plot with colors from 3rd variable

VertexIndices: [] Assuming you used the builtin area function to generate the plot, you can set the FaceAlpha property of the area-plot’s children. 2D colour coded plot with already binned data . Absolutely terrific! colorData = Thank you for this post, it is very useful. I created events listeners for markers in both plot and legends. I found that MATLAB’s scatter command does pretty much exactly what I wanted by setting the (mildly undocumented?) The mesh function creates a wireframe mesh. Whenever this command is called the previous settings are discarded and all areas have the same color and no transparency. EdgeColorType: 'truecolor' Or do I need to manually coded each PRN for each color? I’ve also noticed that none of the changes made using MarkerHandle are reflected by the line properties. The files are available from MATLAB Central as the MarkerTransparency package. So, I have been using errorbar instead of plot, with a ‘fake’ error vector, and a capsize equal to 0. The surf function is used to create a 3-D surface plot. 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 … 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. end In this case, try it with a newer release if you can. Read the post text carefully and try the code snippets one by one. 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 . If you wish to access its undocumented and still unstable functionality in your R2013a, then follow the instructions here: https://undocumentedmatlab.com/blog/hg2-update#testing. A major benefit of this package is that it enables the user to have the semi-transparent markers also appear in the legend. MathWorks ist der führende Entwickler von Software für mathematische Berechnungen für Ingenieure und Wissenschaftler. You can restore the transparency by re-updating hMarkers.FaceColorData following the legend call. —————————————————————————————————- 3D. A colormap is an m-by-3 matrix of real numbers between 0.0 and 1.0. Hi all. he_mh.FaceColorData = uint8(255*[1;0;0;0.3]); Share . MaxTextureSize: 1024 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). MaxFrameBufferSize: 0. Not able to find any documentation on this. 3d plot colorscale xyz. 2D scatter plot with Z-value in color. , yN ), locate the points (xi , yi), with i = 1, 2, . Use quiver to plot vector arrows on a 2D plot, or quiver3 to plot arrows in a 3D plot. By continuing to use this website, you consent to our use of cookies. SupportsAlignVertexCenters: 0 I have the following code that worked for me in the past. I have been using the keepAlpha trick with success as well to keep transparency on the figure Markers when toggling the legend. I would like to know how to make matplotlib’s scatter function colour points by a third variable. set(threednumeric3,'YDataSource','y_new3'); opengl('info') 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 wrote a test for it and yes, reliably works with a pause. However, this works for me just with the filled (heavier) markers like ‘o’, not for the lighter markers like ‘.’ and ‘+’. Hi, I used the suggested script on pc and worked fine. Twitter. I've done this before using scatter easily with the following code: I've done this before using scatter easily with the following code: 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 The default standard function for 2D graph plotting is plot() function. Invalid or deleted object. hLegendComponents = hLegend.EntryContainer.Children; % hLegendComponents has 2 children: child 1 = LegendIcon, child 2 = Text (label) Nothing changed. Thanks so much, adding the drawnow did the trick! Using MATLAB for this purpose allows you to have complete control over the customization of your graph. barColor = barColor * 255; I’ve been looking into hidden lines, axes properties, but I can’t find it anywhere. >> hLine = plot(t,x,'o','LineWidth',2); drawnow; hmarkers = pl.MarkerHandle; for n = 1:5 2D plot by including third parameter as colorbar. Cheers. Hi Yair, age of people). cmap: A map of colors to use in the plot. It used to be that zbuffer would do the trick (loses vector format) but at least the transparency property is not lost. Hi – re your column on assigning transparency to plot markers: I tried the code on a simple example and all was well. Accelerating the pace of engineering and science. drawnow Let’s add more flavor to it. No way to make transparent marker faces / edges on a 3D plot? Have you discovered a similar issue and is there a workaround to this problem? Here's how one can use those colors in MATLAB. 'MarkerEdgeAlpha', 0.3 , ... Version: '1.1.0' Choose a web site to get translated content where available and see local events and offers. Learn more about 2d-plot, colorscale 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). Many statistical analyses involve only two variables: a predictor variable and a response variable. I have been tasked with making a plot with a couple variables of available data. The above does not work on Matlab 2016a. I have no idea whether it is reproducible or how it works, but it does the job for me (Win 10, R2019b). Many thanks in advance. You will then see the transparent markers nicely. hMarkers.FaceColorType = 'truecoloralpha'; Visible: 'on' Then export_fig works its magic and everything looks great (even in pdf!). Or do I have to use the patch command? Do you have any suggestion for this situation? hMarkers.EdgeColorData = uint8(255*[1,0.4,0.6,0.2]'); There is also a possibility that this does not work on R2014b, which was the first Matlab release to officially use the new graphics system (HG2). I find it very annoying that even copying some tutorial lines into my matlab doesn’t help set the target transparent. But it is not working now! FaceColorType: 'truecolor' Because I get the following error trying the same with animatedline: No appropriate method, property, or field 'MarkerHandle' for class 'matlab.graphics.animation.AnimatedLine'. 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’m still finding my way around MATLAB, and unfortunately I’m stuck – was wondering if I can access the hidden MarkerHandle in Matlab 2013a? This will reset back the original color. newcolordata = uint8(repmat(oldcolordata,1,numel(x))); drawnow; You can also select a web site from the following list: Select the China site (in Chinese or English) for best site performance. . hLine.MarkerFaceColor = [0.5,0.5,0.5]; We will begin with a basic plot 3-D line plot. Learn more about scatter, 2d plot, color x=1:10; y=10*x; hLine=plot(x,y,'o-'); drawnow; No transparency. 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 will try a 2016 release on another computer tomorrow. @Lukas – Matlab automatically removes transparency when you modify the axes (e.g., by rotation). BR. I've succeeded in writing a file that plots the points where measurements were done on the already existing map. It seems that you need to set FaceColorType/EdgeColorType to ‘truecoloralpha’ in order to get transparency effect. (refer code) and resulting as photo below. (2) use individual marker sizes to encode a 4th variable (e.g. hm = ha.MarkerHandle; Hi, I was just attempting to control plot marker transparency as described in this tutorial but for a line object made using 200 190 180 170 160 150 140 130 120 110 Such data are easy to visualize using 2D scatter plots, bivariate histograms, boxplots, etc. h(2).Face.ColorData(4) = 90; % =90/255=35% opaque =65% transparent. A few examples of how to use these functions are included in the download and there is also a Wiki on GitHub. Stairs Plot. 25 1 1 silver badge 7 7 bronze badges. I've succeeded in writing a file that plots the points where measurements were done on the already existing map. hMarkers.FaceColorData = uint8(255*[1;0;0;0.3]); % Alpha=0.3 => 70% transparent red - restored after the legend call any idea? FaceHandle.ColorType = 'truecoloralpha'; I have hundreds of 2D-curves in one plot. The property is simply hidden and not displayed when you run the get/set commands, but once you know that it exists you can use it just like any other property. Matlab’s print and saveas functions clear such transparencies, and there is no known workaround for this. However, now I’m wondering if it’s possible to change the marker of a specific subset of plotted points after they’ve already been plotted. 4. @(ObjH, EventData) keepAlpha(ObjH, EventData, cFace, cEdge)); function keepAlpha(src,eventData, FaceColor, EdgeColor) Next time please be more considerate of others. Invalid or deleted object. Plot with color variation from third variable. Extensions: {3x1 cell} Most likely cause is missing [] around left hand side that has a comma separated list expansion.“. 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. So try using the ScreenCapture utility. http://glowingpython.blogspot.co.at/2011/11/how-to-make-bubble-charts-with.html. . @Collin – there is indeed a MarkerHandle property also for plot3, exactly the same as for plot. 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). 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. . VertexData: [3x10 single] EdgeColorData: [4x1 uint8] I am getting a warning message after running the following command, hMarkers.FaceColorData=CMdata; A colormap is an m-by-3 matrix of real numbers between 0.0 and 1.0. hey, i have many lines in X and Y axes, need to color each line according to a variable Z, how to do that ? age of people). LinkedIn. It is simple enough to reset the MarkerHandle properties following a viewpoint transformation but it is a bit of a pain, especially since I would like to explore the 3D point cloud using zoom and rotation. I am currently using R2014b however I cannot even find the property of the marker’s handle. Thanks again for your kind help and for putting this down for others to read! I am facing problems exporting such figures as a pdf/svg to modify it using illustrator, especially when I have multiple subplots! rng(144); Then this works just fine. Related: https://undocumentedmatlab.com/blog/solving-a-matlab-hang-problem, Dear Yair, Sign in to comment. >> hMarkers.EdgeColorData.get %This can neither. I find transparent markers really essential for making dense scatter plots readable. hMarkers.FaceColorData = uint8(255*[1;0;0;0.3]); The dots are still the same color. 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 I use 2014b on Win8. >> hMarkers.EdgeColorData = [1,1,1,0.2]; 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 = hLine.MarkerHandle; Great post. the problem is once exporting either using saveas or print functions, the transparency is not saved and gives a full normal color image! There are several functions available in MATLAB to create 2-dimensional and 3-dimensional plots. @EZ – transparency output is (and always was) problematic in Matlab. Starting in R2019b, you can display a tiling of plots using the tiledlayout and nexttile functions. I can change it to whatever value, but the transparency of the faces (areas) don’t change at all. I just want to share a small trick. However, the color input has to be a matrix. 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 … That would be very ideal. This website uses cookies to improve your user experience, personalize content and ads, and analyze website traffic. hm.FaceColorData = FaceColor; CMdata=uint8([repmat(mCol'*255,1,length(CMtrans)); CMtrans]); Use MATLAB2015b! You should learn to navigate MATLAB's documentation, then … . For some reason on Matlab 2014b the area alpha doesn’t seem to work. asked Aug 14 '12 at 17:39. user1598764 user1598764. hLegendIconComponents = hLegendComponents.Icon.Transform.Children; % child 1 = Marker, child 2 = LineStrip 4D plot - representing 3 variables function. On the screen, I have a nice figure, but once exporting the figure I am loosing all. @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). For example, is there a hidden way to access the handles to the Markers that are in the legend ? MOTOHAWK crashes MATLAB R2013b (3rd party product) How to assign data to axis vol3d; How to set a color for a certan value (without showing that value in the colorbar) Max or Min values of multidimensional array with variable number of arrays (3rd dimension) How to plot monthly means data to show seasonal change over 47 years 'BarWidth' , 0.8 , ... fbarHandle = bar( ax_fBar , ... Yes of course. >> hMarkers.EdgeColorData %This cannot show the current value of the markers. 0 114 189 255 I have three variables (Return, Risk, Supply) where I would like to present them on a scatter plot as the attached. But then I'm supposed to color (from red to blue) each point according to a 3rd variable, which is a derivative of a couple other variables (getting convoluted yet?). Learn more about 4d, 3 variables, function, color representing, color, surface, color surface MATLAB Cool! Java Version: Java 1.7.0_60-b19 with Oracle Corporation Java HotSpot(TM) 64-Bit Server VM mixed mode. hm.EdgeColorData = EdgeColor; age of people). Each … hm.EdgeColorData = cEdge; Thanks again. addlistener(ha,'MarkedClean',... x . Thanks a lot for the trouble shooting. You can change their colors, marker size or any other properties by setting the quiver series properties . @Grunde – Yes this is possible, but I don’t think you need to use any undocumented features for this. 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). @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. Learn more about plot between a matrix, a vector and another matrix I copy/paste your sample and run it. h = area(magic(4)); drawnow; % 1x4 area object @Antonius – the corresponding internal objects in a bar chart are hBarChart.Edge and hBarChart.Face. % keep transparent the scatter plot was prepared for part of the full cell number! Curves are produced by function where is a random variable. 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”. Return the chart line in the output variable p. t = linspace(-10,10,1000); xt = exp(-t./10). 2D plot with 3rd variable. 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). , xN ), and a vector of y-coordinates, y = (y1, . I'm not sure how I would use my z-variable to control color variation if the color input has to be a matrix. Size: 6 Oh, sorry, PlotTbl does not allow the precise control of colors that you want. The lines for data Y1, Y2,…,Yn with respect to their … set([h.Face], 'ColorType', 'truecoloralpha') 128 128 128 255. Is there also a hidden MarkerHandle or something similar for animatedline? Thanks for you reply. I wondered a bit as there were actually nothing different between the code and what I tried yesterday but the last line. And the area object itself doesn’t have a FaceAlpha property. 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 … HTML tags such as or are accepted. drawnow(); hMarkers = hLine.MarkerHandle; % this is fine but returns a 0x0 empty GraphicsPlaceholder array The velocity should be indicated by the color of … 'MarkerFaceAlpha', 0.1); “Throughout today, we’ve 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).”. Importantly, 2015b prints figures properly! Do you know how one can do something similar to a bar chart? It’s a pretty awful hack job to achieve what I feel should be basic functionality but here we go: % generate data shading interp colormap colorcube. SupportsGraphicsSmoothing: 0 Ask Question Asked 5 years, 5 months ago. ans = >> hMarkers = hLine.MarkerHandle; Any idea why that is? I get this: >> drawnow y=10*x; FaceColorData: [4x1 uint8] Best. 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. c: Array of values to use for marker colors. To add plots to an existing figure, use hold on. Hi Dani and Yair, @Pierre – thanks for sharing this clever useful trick, IB-Matlab: InteractiveBrokers-Matlab connector, EODML: EODHistoricalData-Matlab connector, While setting the 'MarkerFaceColor' property of Line: As we can see, we can separately attach transparency values to the marker’s edges and/or faces. threednumeric3=scatter3(x_new3,y_new3,z_new3,'blue') When I asked what this is … I simply had to apply the color and alpha settings at the very end of my plotting script (after settings xlims, adding legends, etc.). x_new3=nan; y_new3=nan; z_new3=nan; Learn more about color coded, imagesc, plotting, custom color grid, heatmap Each specification can include characters for the line color, style, and marker. Would the optimal solution be to create a function myLegend that would design the legend from scratch ? Looks really neat. The Matlab version I’m using is R2019a. No appropriate method, property, or field 'FaceColorData' for Something like that yes, especially the checkered plot. y . Thank you for the terrific post! I have corresponding Z values for X and Y coordinates . In order to customize the legend itself, we need to dig into the legend object’s hierarchy. You can use the ColorSpecs option to assign the colors to your third variable values in any order that you want, but unfortunately you are limited to the single-character color specifications that MATLAB … I have nothing new except or using different dataset (the Matlab version is the same 2016a). Do you have any further details / documentation about ‘MarkerHandle’? L2=scatter(ax,hint.xy(cellsIn,1),hint.xy(cellsIn,2),floor(ms2*frac),mCol,'filled'); E.g. I’m would like to get a better view of many points in a scatter3 plot, but unfortunately the transparency is lost once I rotate the plot. I don't know however how i can plot the 3rd variable, the velocity, on there as well. FaceColorBinding: 'object' LineWidth: 0.5 Hello, Thank you very much!! Of course it still works. hMarkers.get % hence this does nothing But at least I can export my scatter plots now…. Creating Plotting. 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. How to make 3D mesh plot in matlab with three diffrent variables?
