mu.pl.scatter() fails when providing color

[SarahOuologuem]

Hi!

I'm getting the following error when running mu.pl.scatter() with a provided color:

When setting color=None, the plotting function does not fail:

I also checked scanpy's sc.pl.scatter() and it errors as described in scverse/scanpy#1986 and scverse/scanpy#311 when passing the color as a list.

Therefore, when deleting line 75 (color = [color]) in plot.py, i.e. passing the color as a string instead of a list to the function sc.pl.scatter(), mu.pl.scatter() works completely fine and

mu.pl.scatter(data,"rna:CD4","rna:CD8A", color="rna:total_counts")

then produces:

System

• Linux, Ubuntu
• Python version: 3.10
• Versions of libraries involved:
  • scanpy: 1.9.6
  • muon: 0.1.5
