How to save figure without showing it?

[imirzayev]

I want to save the plots in the image without showing them within a loop. However, the plots still pop up even if I do not use show() function.

You should check in Coding Style section of the website here which provides the solution to you're issue.

The example in the link does not seem to work:

auto f = figure(true);
auto ax = f->gca();

yields class matplot::figure_type'} has no member named gca'
