Exporting a figure with transparent markers

9 views (last 30 days)
I need to export a figure with transparent markers. I can not currently find a solution for this. Usually I use export_fig, but this is not working. I have tried plot2svg (which just spits back errors), saveFigure does not work, save2pdf, print, or saving through the interface to any format. Normally I save to .png.
The figure was generated through:
drawnow; hMarkers = hLine.MarkerHandle; hMarkers.get; hMarkers.FaceColorData = uint8(255*[0;0;0;0.5]);
Any help is appreciated

How is it different from having no markers at all or having set the 'MarkerEdgeColor' set to none?

Reaching inside the Line object and messing with its undocumented internals is not a supported operation for a variety of reasons. One of the reasons is that print won't be able to see what you've done.
There are supported ways to create objects with transparency. For example, in R2015b or R2016a, you could do this:
npts = 250;
X = 1:npts;
Y = randn(1,npts);

My university only has matlab version 2015a. On the help files it says that FaceAlpha is possible for scatter objects after 2014b, but this does not seem to be true. I found a way to get around it using patches to make the markers...
