I would like to make the background of a polar histogram transparent to where I can save an image that only shows the grid lines, text, and bins. It does not seem possible with any of the polar axes properties or with exportgraphics. Thank you for any advice.

在 MATLAB Online 中打开

One way that comes to my mind is to save it as eps (or pdf):

set(gcf, 'color', 'none');
set(gca, 'color', 'none');
exportgraphics(gcf, "pic.eps", 'BackgroundColor', 'none', 'ContentType', 'vector') % can also be .pdf
