Hi,
I'm writing a GUI which continuously updates a set of plots within a figure (there are three axes showing, with their separate plots, all within that one figure). What I want to do is to export one of those plots as a png file. My problem is that I can't seem to do that correctly. I've tried a couple of things:
Using imwrite:
axes(myAxes);dataPlot = imagesc(data);dataFrame = getframe(myAxes);[im,imMap] = frame2im(dataFrame);imwrite(im,'fileNameHere');
The problem is that if I'm running the GUI in the background, it saves images of whatever's in the foreground, and not the actual plot that I want.
Using print:
*Plotting like above*print('-dpng','fileNameHere');
But (I think, at least) that works only for entire figures, so it stores the entire GUI frame, which is more than what I need (and it looks more confusing too as an image).
One option, of course, is to create a temporary figure, plot it there and use print, but that slows the processing down a little, and looks really un-cool and un-swift, so I'd prefer to avoid that method.
I've noticed export_fig on File Exchange (which certainly looks like it could do the trick), but I was hoping there would be a simple built-in way of doing this. Is there one? (Pardon my noob-iness, I'm fairly new to Matlab)
Thanks for any help!
