Colorbar zoom not working

[pordyna]

Hi, I found a minor problem. This maybe not an error, but a nice feature that plopp misses due to not using Matplotlib directly for applying the colormap. Wwhen using the widget backend in jupyter the zooming into the colorbar changes the range on the colorbar but doesn't update the vmin, vmax in the plot as it works with plain matplotlib.

Hi @pordyna, thanks for the report.
Yes we are not currently using that feature. The colormapping is, as you noticed, done outside of the matplotlib backend.
While it is very likely that we will continue to use Matplotlib as our main backend in the coming years, we have designed Plopp to not be entirely tied to it.

Hooking a callback from the axis zoom, all the way up to the Colormapper doesn't seem nice/trivial.
At the same time, being able to change the limits dynamically without having to regenerate the plot when you are exploring your data sounds like something nice to have...
