How do you save a figure with a trasparent background? I want to save a figure as a png image that has a transparent background so I can put the image into PowerPoint and the PowerPoint graphic will show through the Matlab figure.

The most recent version of export_fig includes a -transparent option for .png export

Sorry for the late response. If you did not solve it already perhaps you can upload the code and I will have a look.
The first option calls the current axis (gca), so it should be located after the figure. The other option should be at the beginning of the code.

Non matlab way, Can use gimp software to remove white background from image, by selecting the background with color select tool, invert selection and copy. Then create new gimp window with background option as tranperancy, and paste it into that and export that as png. Not programmable but can be used to prepare images for presentation.

since Matlab R2020a, use "exportgraphics", for example ,you can do like this
x = 0:.1:2*pi;
y = sin(x);
% save to transparented image
set(gcf, 'color', 'none');
set(gca, 'color', 'none');
exportgraphics(gcf,'transparent.eps',... % since R2020a
