Changing scale for plotting functions

Hello there,

Is it possible to customise the expression range scale when using for example pl.umap? I thought I could try use_raw=True, but got the same issue as in #370.

Thank you for your help!

you can use vmin and vmax to control the scale range. You can also change the colormap using cmap. For example:

rcParams['figure.figsize'] = 4,4
adata = sc.datasets.pbmc68k_reduced()
sc.pl.umap(adata, color=['CD3D'], use_raw=False, cmap='bwr', vmin=-3, vmax=3)

We are discussing that at the moment. See https://github.com/theislab/scanpy/issues/775
