What Ive gathered so far is that this may be related the necessity of using the drawnow command in between plotting the line and getting the line marker handles. cd2 = uint8(cd2'*255); % need a 4xN uint8 array Making statements based on opinion; back them up with references or personal experience. @James try using the opengl (rather than painters) renderer (the -opengl parameter in export_fig). >> x.MarkerFaceColor(4) = 0.5; When I do the export, I simply get the figure without my edited properties like alpha and color interpolation. This is because the markers have the same color as the lines in todays example. Here's one possible approach: explicitly plot each segment of the line with a different color taken from the desired colormap. I am looking to get a vector graphic version of one of these figures, any help would be great!

In some rare cases (e.g., for patch objects) Matlab has separate Alpha properties that are fully documented, but in any case nowhere have I seen documented that we can directly set the alpha value in the color property, especially for objects (such as plot lines) that do not officially support transparency. Pingback: Colored longitudinal river profiles TopoToolbox. I used your code to draw a transparent line. LineStyle: 'solid' Color value must be a 3 element numeric vector. I implemented the surface []. In some rare cases (e.g., for patch objects) Matlab has separate Alpha properties that are fully documented, but in any case nowhere have I seen documented that we can directly set the alpha value in the color property, especially for objects (such as plot lines) that do not officially support transparency. This stuff is quite common in visualisation tools such as VisIt and ParaView but I could not yet FIGURE it out in Matlab. I used allchild to get handles of the subobjects and set the FaceAlpha to less than 1, [~, hContour] = contourf(peaks(20), 10); @Sina you need to access the individual contour lines, and then change the lines ColorType from truecolor to truecoloralpha, as I explained multiple times on this page. offers.

For further learning on colormaps, a different colorful method of visualizing data, check out the video . newColor = uint8(newColor); Learn more about colormap, random colors . @thephysicsguy: I updated my answer. ), so the result would be similar to one in image below? Here are the codes, which are mostly exactly as yours. I would also like to have a colormap legend kind of thing showing the color gradient and it's actual representation of z. When I try to render with vector graphics or .bmp with increased resolution, I get only the changes I made that dont rely on the drawnow (so it renders the grid lines, but not the color and alpha values based on line.MarkerHandle.EdgeColorData). Based on drawnow % Will not work, if this command is not issued Does an Antimagic Field suppress the ability score increases granted by the Manual or Tome magic items? hFaces(faceIdx).ColorType = 'truecoloralpha'; % default = 'truecolor' Then we can modify Edge.ColorData from being a 41 array of uint8 (value of 255 corresponding to a color value of 1.0), to being a 4xN matrix, where N is the number of data points specified for the line, such that each data point along the line will get its own unique RGB or RGBA value. If I dbstep through each iteration of the loop, then the color will show up, however, when the loop completes the gradient colors go away and the default uniform matlab colors remain. Bode plot. In this case, the total number of line is assumed to 100. c = interp1([1;100],[cStart;cEnd],(1:100)'); Now is there an elegant way to do that (without a for loop) ? PickableParts: 'visible' WideLineRenderingHint: 'software' hold on . Specifically, I am trying to save a vector format (pdf, eps, or similar) with h2b-style multicolor lines. Im using 2013b, maybe its different in later versions? Is there a possibility to solve that problem? Layer: 'middle' xlim([1,5]); I tried to use the code for varying the transparency and for some reason the following example code does not work as expected: I expected first 5 points to have transparency of 200 and then 5 with transparency of 100. This time it works and the line is transparent as your results. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. I do not need the drawnow to do to things such as changing the grid lines (so documented properties related to the axes rather than the line). Also try using bitmap output with a large resolution (the -r# parameter) it would not be vectorized, but at least it might have a large-enough resolution to be publication quality. Repeating the procedure with more points than that results in a warning and no color gradient: To fix the issue, we need to probe the number of vertices in hPlot.Edge: But, if we try, say, to resize the figure, the warning reappears (though the gradient stays): Similar unexpected behavior occurs in zoom, copyobj etc. When I try that code, hFaces comes out as 0x0. h2b = plot(2:6, 15:-1:11, '.-r', 'LineWidth',8, 'DisplayName',' 0.7'); Is it viable to have a school for warriors or assassins that pits students against each other in lethal combat? I guess the reason is that when it runs the setting process, the figure is still unfinished? I am plotting multiple lines in a for loop. How to change the color of an svg element? Add a call to hold(on) before you plot to ensure that both lines are ploted and not deleted. Thanks. https://www.mathworks.com/matlabcentral/fileexchange/3225-quiverc, https://www.mathworks.com/matlabcentral/fileexchange/7180-quiverc2wcmap, https://www.mathworks.com/matlabcentral/fileexchange/31480-quiverc-m-updated-with-new-features, You may receive emails, depending on your. Array is wrong shape or size I know that the rgb colors I need to use are the following: [1 1 1], [0.9 0.9 0.9], [0.8 0.8 0.8], , [0.2 0.2 0.2] and [0.1 0.1 0.1] but when I use them in the plot command it fails to work, all lines appear to have the same color. I dont know if export_fig would be able to deal with such a change. drawnow (if the line is tilted, then the gradient would be still perpendicular to that line). But there are some problems. All those years I used a 2N mesh in order to make a gradient plot, and it turns out to be so simple in HG2. cd = [uint8(jet(N)*255) uint8(ones(N, 1))].; Because I would like to use it to generate some pictures and its a disaster if I have to run the last sentence in Command Window each time. There is a FEX tool that can do a colormapped quiver plot. 'FaceColor', 'none', do not draw the faces, 'EdgeColor', 'interp', interpolate between vertices. sites are not optimized for visits from your location. I guess any further advice, tips or even a solution would be greatly appreciated. @Sina you need to access the individual contour lines, and then change the lines ColorType from truecolor to truecoloralpha, as I explained multiple times on this page. Then I run the last sentence again in the Command Window, which is shown below. See code below taken from ``Area plot with gradient"--Patrick Kalita's answer on 16 Feb 2011: % Def. you try to modify the line before Matlab has completed its on-screen rendering). So, for example, [1, 0, 0, 0.3] means a 70%-transparent red. I need to create a gradient of these lines (each line representing a different time point) to show that the lines gradually shift down. hFig.Position = [0.2 0.2 0.5 0.6]; Similar unexpected behavior occurs in zoom, copyobj etc. To learn more, see our tips on writing great answers. how to generate colors for line plot. I have no current idea how to fix this. Have you managed to get the same working for markers? IB-Matlab: InteractiveBrokers-Matlab connector, EODML: EODHistoricalData-Matlab connector, Warning: Error creating or updating LineStrip The issue was that I was using row vectors of data, but you appear to have column vectors of data. I very much wanted this to work with Quiver, and it does as long as the number of points is not too big. Is there a way to have a gradient going from top to bottom? tractHandle = plot3(tctData{tmpTctID}(:,1),tctData{tmpTctID}(:,2),tctData{tmpTctID}(:,3)); set(h2b.Edge, 'ColorBinding','interpolated', 'ColorData',cd , 'ColorType','truecoloralpha'); The codes are almost exactly as yours, except that I set the ColorType since it is truecolor in default. Error in value of property ColorData Strange. So, for example, [1, 0, 0, 0.3] means a 70%-transparent red. So stay tuned . Unable to complete the action because of changes made to the page.
