matlab 2d plot with colors from 3rd variable

The lines drawn from plot function can be continuous or discrete by nature. BR. Most likely cause is missing [] around left hand side that has a comma separated list expansion.“. c: Array of values to use for marker colors. I tried this with R2016b and ran into similar issues when trying to export, i.e. For some reason on Matlab 2014b the area alpha doesn’t seem to work. I am, as Dani, very keen to find a solution to keep the transparency in the legend markers as well. 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 have a question on printing figure to pdf (or any format really!) Renderer: 'GDI Generic' hMarkers = threednumeric3.MarkerHandle; % a matlab.graphics.primitive.world.Marker object Using MATLAB for this purpose allows you to have complete control over the customization of your graph. It’s the same as 2-D plot with addition of 3rd vector (array). hLine.MarkerFaceColor = [0.5,0.5,0.5]; while when the operation is successful, the class is: age of people). % this is fine but returns a 0x0 empty GraphicsPlaceholder array, % Alpha=0.3 => 70% transparent red - restored after the legend call, % hLegendComponents has 2 children: child 1 = LegendIcon, child 2 = Text (label), 'Visual 0x0e, (RGB 24 bits (8 8 8), Z ...'. As far as I tested, the above is not true for R2016b. I was wondering if you have had any success in using other renderers? Curves are produced by function where is a random variable. Hi, I used the suggested script on pc and worked fine. MathWorks ist der führende Entwickler von Software für mathematische Berechnungen für Ingenieure und Wissenschaftler. Is there a way to convince ‘legend’ to show the transparent markers properly too? matlab: scatter plots with high number of datapoints. he_mh = he.MarkerHandle; This will reset back the original 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 Warning: Error creating or updating Marker http://glowingpython.blogspot.co.at/2011/11/how-to-make-bubble-charts-with.html. With the help of MATLAB (Matrix Laboratory), you'll be able to create stunning 3-D visuals with the data you provide. Next time please be more considerate of others. Entering Edit Plot mode (the pointer icon on the toolbar) resets the ColorBinding and ColorData back to ‘object’ and the original color. y: Array of values to use for the y-axis positions in the plot. hMarkers = hLine.MarkerHandle; 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). Array contains incorrect data values. Lastly I found this would be the key: >> hLine = plot(1:5,2:6,'o','LineWidth',2); drawnow; 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). >> hMarkers = hLine.MarkerHandle; I've done this before using scatter easily with the following code: I've done this before using scatter easily with the following code: Am I missing something? Then this works just fine. Is that the case? hm.EdgeColorData = EdgeColor; As far as I can tell, changing the EdgeColorBinding (or FaceColorBinding) from ‘object’ to ‘interpolated’ or ‘discrete’ is problematic. hm.FaceColorData = FaceColor; Visible: 'on' By default, the color of the mesh is proportional to the surface height. Or do I have to use the patch command? (refer code) and resulting as photo below. , xN ), and a vector of y-coordinates, y = (y1, . oldcolordata = hmarkers.EdgeColorData; set(threednumeric3,'ZDataSource','z_new3'); I’m trying this in matlab r2015a, I got the same problem as Fabian, but the drawnow command does not solve the problem. But then I'm supposed to color (from red to blue) each point according to a 3rd variable… end, Note that when adding a legend the symbol comes up wrong. Hello, Do you have any further details / documentation about ‘MarkerHandle’? Return the chart line in the output variable p. t = linspace(-10,10,1000); xt = exp(-t./10). There are several functions available in MATLAB to create 2-dimensional and 3-dimensional plots. age of people). 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). 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. x=1:10; y=10*x; hLine=plot(x,y,'o-'); drawnow; Vendor: 'Microsoft Corporation' I've succeeded in writing a file that plots the points where measurements were done on the already existing map. I don't know however how i can plot the 3rd variable… Sign in to answer this question. As we can see, we can separately attach transparency values to the marker’s edges and/or faces. I find it very annoying that even copying some tutorial lines into my matlab doesn’t help set the target transparent. Use MATLAB2015b! Or at least I’ve figured out how to avoid it. . >> ver 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 want to change size of Brushing marker. By continuing to use this website, you consent to our use of cookies. Reading back, it looks like another user has also mentioned this – pause(1) (shorter is possibly fine too) resolved the error. h = area(magic(4)); drawnow; % 1x4 area object I'm to make a normal 2D scatter plot of the data with respect to 2 of the variables given, easy enough. Unable to complete the action because of changes made to the page. I simply had to apply the color and alpha settings at the very end of my plotting script (after settings xlims, adding legends, etc.). hMarkers.get Hey Guys, I've been trying to make a map which has indicators for the velocity that has been measured. I wondered a bit as there were actually nothing different between the code and what I tried yesterday but the last line. , yN ), locate the points (xi , yi), with i = 1, 2, . X,Y, and Z. X & Y are coordinates and Z is a value. The comment of Arnold there is weird though. . 200 190 180 170 160 150 140 130 120 110 Most of the plotting related functions in MATLAB are covered by the pylab module. Thanks again. Also see related: Because I get the following error trying the same with animatedline: No appropriate method, property, or field 'MarkerHandle' for class 'matlab.graphics.animation.AnimatedLine'. Whenever this command is called the previous settings are discarded and all areas have the same color and no transparency. I'm not sure how I would use my z-variable to control color variation if the color input has to be a matrix. In this case, try it with a newer release if you can. While there are appropriate object properties (Size for the Line class, and MarkerSize for the MarkerHandle class), these are apparently required to be scalars. Matlab’s print and saveas functions clear such transparencies, and there is no known workaround for this. I have been tasked with making a plot with a couple variables of available data. surf(z) Surface Plot (with Shading) The surfl function creates a surface plot with … y=10*x; A line drawn with Matlab is feasible by incorporating a 2-D plot function plot() that creates two dimensional graph for the dependent variable with respect to the depending variable. In any case, your code was buggy in the sense that EdgeColorData expects a uint8 column array of values (as explained in my posts). Plotting is a graphical representation of a data set that shows a relationship between two or more variables. 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. Thanks a lot for the very useful hack. '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).”. 4. I was just trying this on a plot and get: h = plot(1:1:5, 'bo'); My z-variable is also a 1xn vector. An eye-opener 🙂. 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. line([1,5:9], [1,5:9], 'LineStyle','none', 'marker','o', 'MarkerFaceColor','r'); % red circle markers This is not too difficult: hLegend = legend('on'); I have written a collection of Matlab functions for creating semi-transparent markers in plots and legends. @(ObjH, EventData) keepAlpha(ObjH, EventData, cFace, cEdge)); function keepAlpha(src,eventData, FaceColor, EdgeColor) 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. Matlab can quite easily plot figures in 3D, so a 4D plot is a straightforward extension. But since you neglected to come back here and update that you have found a solution, causing me and other readers extra effort to look for a solution, I thought it would at least be nice of me to inform other readers here that a solution was found. thank you very much for these very valuable tips! To make life easier, all files you save and … I have three variables (Return, Risk, Supply) where I would like to present them on a scatter plot as the attached. Share . 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). Visual: 'Visual 0x0e, (RGB 24 bits (8 8 8), Z ...' Please see our. cEdge = uint8(255*[0 0 0 0.3])'; LineWidth: 0.5 set([h.Face], 'ColorType', 'truecoloralpha') Any idea what’s going on? I have corresponding Z values for X and Y coordinates . SupportsAlignVertexCenters: 0 I created events listeners for markers in both plot and legends. You can also select a web site from the following list: Select the China site (in Chinese or English) for best site performance. could anyone help me with this? Any idea on that? EdgeColorType: 'truecolor' You could attach a callback listener to the axes’ MarkedClean event that will restore the transparency once Matlab finishes doing its internal updates. Then export_fig works its magic and everything looks great (even in pdf!). hMarkers = L2.MarkerHandle; Invalid or deleted object. 0 114 189 255 I've succeeded in writing a file that plots the points where measurements were done on the already existing map. Style: 'circle' The mesh function creates a wireframe mesh. yData = normrnd(1, 0.2, 1000, 1); Clicking the Edit Plot icon will reset all markers. 210 215 220 225 230 235 240 245 250 255 EdgeColorData: [4x1 uint8] You can restore the transparency by re-updating hMarkers.FaceColorData following the legend call. One more question: in MATLAB, I frequently need to generate a 2D scatter plot with: @Pierre – thanks for sharing this clever useful trick, IB-Matlab: InteractiveBrokers-Matlab connector, EODML: EODHistoricalData-Matlab connector, While setting the 'MarkerFaceColor' property of Line: %This cannot show the current value of the markers. Thanks a lot for the trouble shooting. 6. hMarkers.FaceColorType = 'truecoloralpha'; plot3. Thanks so much, adding the drawnow did the trick! Active 1 year, 2 months ago. My code looked something like this: scatter(X, Y, 6, 'filled', ... 0 Comments. x=1:10; y=10*x; hLine=plot(x,y,'o-'); drawnow; Thanks, this is useful — setting an alpha component is a better way to visualise density than applying jitter. Open Live Script. s: The marker size. PickableParts: 'visible' Use quiver to plot vector arrows on a 2D plot, or quiver3 to plot arrows in a 3D plot. hm.EdgeColorData = cEdge; Parent: [1x1 Line] Starting in R2019b, you can display a tiling of plots using the tiledlayout and nexttile functions. Find the treasures in MATLAB Central and discover how the community can help you! At the beginning of each Matlab session, it is important to select your working folder. ans = h = area(magic(4)); drawnow; % 1x4 area object I want to know is it possible to make the data color in one by one color (e.g: Black, and another 30 colors according to total PRN) and not in gradient as below? The keepAlpha of Fabian does a good job preventing Matlab to get rid of the transparency again when, e.g., legend is called. @Hassan – check perhaps a different figure renderer is used on your two computers. Thanks for any help. Any help? 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 cFace = uint8(255*[0 0 1 0.1])'; For example, is there a hidden way to access the handles to the Markers that are in the legend ? barColor = barColor * 255; for n = 1:5 hLegendComponents = hLegend.EntryContainer.Children; % hLegendComponents has 2 children: child 1 = LegendIcon, child 2 = Text (label) (2) use individual marker sizes to encode a 4th variable (e.g. Thank you for this post, it is very useful. @Lukas – Matlab automatically removes transparency when you modify the axes (e.g., by rotation). However, when I use errorbar the transparency settings are kept. * https://undocumentedmatlab.com/blog/customizing-histogram-plots, I tried using hBarChart.Face to change the colors of the bars, but it did not work.

Each … Your post solves this (2) use individual marker sizes to encode a 4th variable (e.g. Do you have any idea or suggestion? Looks really neat. Any hint into where to look for a begining of solution would be very welcome. I found an issue, though I don’t think it’s related to this method “per se”. @Philip – If you use scatter or scatter3, then you can set the SizeData property to be either a scalar or a vector the same size as the data. class 'matlab.graphics.chart.primitive.Line'. We also chose to move the legend in the area of extrapolation. You can use a screen capture utility to capture the actual appearance and then print from that screen-capture. 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 … Thanks a lot. 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. 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). @Yair, I just saw your response. Learn more about color coded, imagesc, plotting, custom color grid, heatmap x_new3=nan; y_new3=nan; z_new3=nan; Adding a pause in front of setting the alpha value makes it reliable again. and retaining the transparency.

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. Based on your location, we recommend that you select: . >> hMarkers = hLine.MarkerHandle; the transparency would be lost. Hey Guys, I've been trying to make a map which has indicators for the velocity that has been measured. h(2).Face.ColorData(4) = 90; % =90/255=35% opaque =65% transparent Let’s add more flavor to it. 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. The Matlab version I’m using is R2019a. A major benefit of this package is that it enables the user to have the semi-transparent markers also appear in the legend. You can try to place your customization code in a short function that you’d reference in the axes CreateFcn property and/or its MarkedClean event (using addlistener). shading interp colormap colorcube. Did I ever say “h.FaceColorData” (where h is the plot return handle) anywhere in my post? 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”. I will try a 2016 release on another computer tomorrow. addlistener(ha,'MarkedClean',... matlab 2d. Still, have the same problem. Choose a web site to get translated content where available and see local events and offers. FaceHandle = get(fbarHandle.Face); However, the color input has to be a matrix. newcolordata(:,1) = [255;0;0;255]; % Turn the first marker red Hi Yair, For performance reasons, I would like to avoid calling ‘line’ several times in a loop. Hi. I would like to know how to make matplotlib’s scatter function colour points by a third variable. 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. drawnow The velocity should be indicated by the color of … Go to Home Layout Default. Starting in R2019b, you can display a tiling of plots using the tiledlayout and nexttile functions. 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 … set(hMarkers,'FaceColorBinding','interpolated', 'FaceColorData',CMdata); solved. I finally have my transparent scatter plots back in 2015a! Thank you very much!! Many thanks in advance. Sign in to comment. Nothing changed. Reload the page to see its updated state. >> hLine = plot(t,x,'o','LineWidth',2); drawnow; So you can use 1/255[255,0,0] to get the color of red to use as a color in MATLAB. They really open up a plethora of charting options that come in very handy, in my case. z=1 ... %You can choose other values and see the difference surfl(z); % surface plot with color-based lighting. Hi all. The default standard function for 2D graph plotting is plot() function. L2=scatter(ax,hint.xy(cellsIn,1),hint.xy(cellsIn,2),floor(ms2*frac),mCol,'filled'); Thanks. Yes of course. Show Hide all comments. @Collin – there is indeed a MarkerHandle property also for plot3, exactly the same as for plot. On the screen, I have a nice figure, but once exporting the figure I am loosing all. I found that MATLAB’s scatter command does pretty much exactly what I wanted by setting the (mildly undocumented?) FaceHandle.ColorBinding = 'interpolated'; —————————————————————————————————- hMarkers.FaceColorData = uint8(255*[1;0;0;0.3]); Hi! I also found I needed to build in a brief pause in my script before obtaining the marker handle to avoid getting the following error: “Too many outputs requested. MATLAB plots play an essential role in the field of mathematics, science, engineering, technology, and finance for statistics and data analysis. Each specification can include characters for the line color, style, and marker. Hi, I was just attempting to control plot marker transparency as described in this tutorial but for a line object made using Thanks for writing this post. I am currently using R2014b however I cannot even find the property of the marker’s handle. There is also the possibility that this is due to your use of OpenGL emulation mode (software=’true’). MATLAB: How to plot 3D data on 2D coordinate system with 3rd item indicated by color scale. 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. It used to be that zbuffer would do the trick (loses vector format) but at least the transparency property is not lost. Cheers. In these cases, the class of this empty object is “Matlab.graphics.GraphicsPlaceholder” 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. @Grunde – Yes this is possible, but I don’t think you need to use any undocumented features for this. 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. Of course it still works. ha = plot(xData, yData, 'ko'); Great post. Last week I explained how to customize plot-lines with transparency and color gradient. Or do I need to manually coded each PRN for each color? Importantly, 2015b prints figures properly! You may receive emails, depending on your. This can be achieved by using the stat_contour aesthetic over the scale_fill_manual aesthetic. . Software: 'true' EZ. number of people). Peter Rochford’s function which was an implementation of this didn’t work starting with r2018b anymore as he writes at the file exchange I'm to make a normal 2D scatter plot of the data with respect to 2 of the variables given, easy enough. 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. This tutorial is Automatically plot with different color lines. opengl('info') Here's how one can use those colors in MATLAB. To add plots to an existing figure, use hold on. However, many datasets involve a larger number of variables, making direct visualization more difficult. MATLAB: 2D plot with 3rd variable. export_fig is exporting the figure without applying the transparency to the markers. FaceHandle.ColorType = 'truecoloralpha'; >> hMarkers.EdgeColorData = uint8(255*[1,0.4,0.6,0.2]'); %works fine Related: https://undocumentedmatlab.com/blog/solving-a-matlab-hang-problem, Dear Yair, 'MarkerEdgeAlpha', 0.3 , ... % plot and make transparent For example: hMarkers.FaceColorData = uint8(255*[1;0;0;0.3]); % Alpha=0.3 => 70% transparent red, >> colorData = uint8([210:5:255; 0:28:252; [0:10:50,40:-10:10]; 200:-10:110]) I don't know however how i can plot the 3rd variable, the velocity, on there as well. y . However, this works for me just with the filled (heavier) markers like ‘o’, not for the lighter markers like ‘.’ and ‘+’. (1) use individual marker transparencies to encode a 3rd variable (e.g. >> hMarkers.EdgeColorData %This cannot show the current value of the markers. drawnow(); ok, shame on me Yair, obviously it wasn’t the plot handle, might have been too late.
