Description

Playing around with the exemplar-002 dataset I noticed that if I link the 4 labels layers and I try plotting the matrix on top the result is wrong:

  • the layers name don't get updated
  • the labels get colored, but with a wrong color.

I suspect that the wrong color is due to a wrong scaling of the colormap, that is normalized to a single layer instead of all the 4 layers.

I think that we can fix this. This would lead to a convenient user experience to plot genes onto multiple layers at once.

Research direction

Reproduce the problem with the exemplar-002 dataset by linking the four labels layers and plotting the matrix on top. Inspect the linked-layer plotting behavior, focusing on layer-name updates and colormap normalization across all four layers; done means names update and label colors use the correct shared scale.
