cmap: A map of colors to use in the plot. Thanks again. Here you are the command lines I used. z=1 ... %You can choose other values and see the difference surfl(z); % surface plot with color-based lighting. I have a question on printing figure to pdf (or any format really!) It seems like there is no MarkerHandle object created when using plot3. This tutorial is Automatically plot with different color lines. Do you have any suggestion for this situation? Until you use hold off or close the window, all plots appear in the … X,Y, and Z. X & Y are coordinates and Z is a value. 'LineWidth' , 0.25 ); thank you very much for these very valuable tips! I had another look and of course you’re right, it works. Open Live Script. Is there a way to convince ‘legend’ to show the transparent markers properly too? 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). Thank you for this post, it is very useful. On the top, you will see a bar with your current folder. So you can use 1/255[255,0,0] to get the color of red to use as a color in MATLAB. . %This cannot show the current value of the markers. Warning: Error creating or updating Marker I have three variables (Return, Risk, Supply) where I would like to present them on a scatter plot as the attached. You’ll probably still run into limitations with either of these though. drawnow; Thanks so much, Yair. 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 … For some reason on Matlab 2014b the area alpha doesn’t seem to work. For example: line(1:10, 1:10, 'LineStyle','-'); % original line with no markers Take A Sneak Peak At The Movies Coming Out This Week (8/12) Weekend Movie Releases – January 15th – January 17th Style: 'circle' One more question: in MATLAB, I frequently need to generate a 2D scatter plot with: Or do I have to use the patch command? In any case, your code was buggy in the sense that EdgeColorData expects a uint8 column array of values (as explained in my posts). FaceHandle = get(fbarHandle.Face); EdgeColorType: 'truecolor' I created events listeners for markers in both plot and legends. opengl('info') so I guess this ‘hack’ doesn’t work anymore. @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. Most of the plotting related functions in MATLAB are covered by the pylab module. But at least I can export my scatter plots now…. I copy/paste your sample and run it. 'MarkerFaceColor', [0 114 189]/255, ... Is it possible to make the area plots transparent? The legend function clears marker customizations such as transparency. x=1:10; y=10*x; set([h.Face], 'ColorType', 'truecoloralpha') And the area object itself doesn’t have a FaceAlpha property. I am getting a warning message after running the following command, hMarkers.FaceColorData=CMdata; The area object doesn’t have any children. add a … hLegendMarker.FaceColorData = uint8(255*[1;0;0;0.3]); % Alpha=0.3 => 70% transparent red, Hi Yair, I've done this before using scatter easily with the following code: I've done this before using scatter easily with the following code: 210 215 220 225 230 235 240 245 250 255 Use MATLAB2015b! But when I try to print, Matlab2014b clears everything. hMarkers.FaceColorData = uint8(255*[1;0;0;0.3]); % Alpha=0.3 => 70% transparent red x=1:10; y=10*x; hLine=plot(x,y,'o-'); drawnow; @(ObjH, EventData) keepAlpha(ObjH, EventData, cFace, cEdge)); function keepAlpha(src,eventData, FaceColor, EdgeColor) I have been tasked with making a plot with a couple variables of available data. @Collin – there is indeed a MarkerHandle property also for plot3, exactly the same as for plot. barColor = barColor * 255; Let’s add more flavor to it. 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 have been tasked with making a plot with a couple variables of available data. 'BarWidth' , 0.8 , ... 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). The files are available from MATLAB Central as the MarkerTransparency package. [-5,5]. hMarkers.FaceColorType = 'truecoloralpha'; hm.EdgeColorData = cEdge; However, when I moved to mac the same script stop working, and I have not transparency gradient. 0 114 189 255 newcolordata(:,1) = [255;0;0;255]; % Turn the first marker red set(threednumeric3,'YDataSource','y_new3'); However, many datasets involve a larger number of variables, making direct visualization more difficult. any idea? Viewed 18k times 11. Here's how one can use those colors in MATLAB. plot3. 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. Looks really neat. the transparency would be lost. oldcolordata = hmarkers.EdgeColorData; @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've succeeded in writing a file that plots the points where measurements were done on the already existing map. asked Aug 14 '12 at 17:39. user1598764 user1598764. set([h.Face], 'ColorType', 'truecoloralpha') 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. I need to plot a color codded 2d graph between 1st and 2nd variable and color has to put as height of 3rd variable. I have the following code that worked for me in the past. Hi. Cheers. FaceHandle.ColorData = barColor; @Antonius – try to add drawnow; pause(0.1); after the creation of the bar, before the use of the Face property. Thanks for all the useful tips. Go to Home Layout Default. MaxTextureSize: 1024 while when the operation is successful, the class is: hMarkers = threednumeric3.MarkerHandle; % a matlab.graphics.primitive.world.Marker object hMarkers = hLine.MarkerHandle; Thanks for any help. EdgeColorBinding: 'object' >> hMarkers.EdgeColorData' % 4-element uint8 array I can change it to whatever value, but the transparency of the faces (areas) don’t change at all. an example of what I’m talking about can be found here: Sweet. 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 … Still, have the same as 2-D plot with a newer release if you can density than applying jitter transparency.
