Does anyone know the status of development for Matplotlib persistent figure saving? I would like to be able to save the figures from matplotlib in an editable form, without flattening down to an image file. The closest thing to this right now is the SVG output, but a native mpl format would be better. I need to be able to save the figure, so that later it can be loaded, edited, and re-saved. I know that this topic has been somewhat discussed in the past, but I believe it is desperately needed, so I thought I would bring it back up.
Let me say why I think this feature is so essential. Anyone who is in research or academia knows that figures often need to be edited when a publication comes back from peer review. It’s already happened to me many times, and I’ve learned that I absolutely have to save my figures for later editing to save myself a lot of time. Some people have argued that a script that generates the plots/figures should be saved, and that if you need to edit the figure, just re-run the script. The problem with this argument is that scientific plots often take hours, days, or even weeks of computation to generate. For example, generating a bit-error-rate curve in communications takes days. Therefore, always re-running from a script is just not practical.
Now, I understand that resources are limited, so I would be willing to raise some money to get this feature added to Matplotlib. It’s desperately needed by myself and many others in the community. I would really like to completely replace Matlab with Python,Scipy, and Matplotlib. MPL is an excellent tool, and it could be even more useful/professional with the addition of a figure save feature.
