How to print figure to an .eps file properly?

I'm printing the same figures as .png and .eps files. The .png looks fine, but the .eps appear to have some issues:

• Somehow the image is cut to minimal space, but it also appear to cut the last number in my X axis.
• My Y axis is set to a log scale, and so the 10^x (x=0,1,2,...) numbers don't look good at all (they look fine in the .png file).
• In the legend of one of my figures there is an equation using sprintf(...). The text there doesn't scale properly with the box of the legend - it goes beyond the box untill it is cut in the bounds of the image.

I'm using the commands:

...
print(figure_current,'-dpng','-r200',file_figure_png_full_location);
...
print(figure_current,'-depsc','-painters',file_figure_eps_full_location);

Try using '-opengl' rather than '-painters' for the renderer.

Been away for abit. I tried this today and strangely it worked. When I looked up this issue I actually saw people recommending to use '-painters' for .eps, so I didn't think of using something else. Any idea why does '-painters' not work properly, and '-opengl' does?

I can't give you a satisfying answer to "why?". My suggestion was based on seeing this statement in the Vector Graphics File section of the documentation for print:

"The default figure renderer is OpenGL. If the figure renderer differs from the renderer used when generating output, some details of the saved figure can differ from the figure on the display. If necessary, you can make the displayed figure and the saved figure use the same renderer. Set the Renderer property for the figure or specify the renderer input argument to the print function."

And I had noticed that you had changed the renderer for the eps file, so that seemed a likely culprit.

When I first tried this, I didn't put a renderer at all, and it gave me the same results I had with '-painters'. Doesn't this mean that '-painters' is default for print?

If I recall correctly, print selects the renderer based on the image format (pixel or vector). That should be mentioned in the doc.

I don't recall for sure, and I'm currently on a machine that doesn't have MATLAB installed (horrors!) so I can't check. But I think the default renderer might be something like "Auto", meaning that the MATLAB will choose which one to use based on properties of the figure. I poked around the documentation a bit, but could not find a definitive answer.

Try using export_fig.

Before resorting to trying to use this external elaborate shared library tool, isn't there a way to just properly save a figure as an .eps file in Matlab?
