Work directory is changed when saving a plot

Hi,

When I save a plot using the toolbar save function, and I save to a different directory than the one where my program is, my program can no longer locate the icons (used in my GUI) that I am using in my .\ressources directory. So saving the plot changed the working directory of my program?

How do I change it back? Isn’t this an error in matplotlib?

Thanks
Soren

Which backend are you using? I don't see any explicit calls to chdir in matplotlib that would make this happen. It would certainly be unintentional if it is.

I don't know about any other back-ends, but the wx FileDialog has an option to change the working dir when the user selects a file I also don't know if this flag is set in the MPL code, but it shouldn't be.

I'd say yes, but it's also an error in the design of your code -- as you've discovered, the working dir is a tenuous concept -- you should set that resources dir in your code start-up and keep it around for when you need it.

wxPython has wx.StandardPaths which can be helpful for finding your aps data, etc -- I'm sure the other toolkits have something, too.
