Plotting fit results via a non-interactive show_fit?

[tikk3r]

The show_fit function currently nicely shows the results of a fit in an interactive way. Perhaps I've missed an option already existing, but I would find it useful if this function could also have the ability to export it to a static image instead of an interactive window. That way I could run it in a scripted fashion on a bunch of images and visually inspect the fits the afterwards.

Indeed, it's not currently possible to do the plotting non-interactively, but it shouldn't be too hard to implement I think. Perhaps controlled through a "filename" option, that when present would cause it to save the plots to a file and exit... I'm not sure if it would always work well though at the default zoom, etc. -- for example, large images with lots of sources might result in it plots that are hard to read.

Yeah for large images I presume it'll give crowded plots that may be hard to interpret. At the moment I am looking at small cutouts of individual sources where it helps me to see the island boundaries, for example. As a local workaround I replaced the plt.show with plt.savefig, which suits my needs for now, but thought it might be a nice-to-have feature to have officially in there.
