Interactive control of color map? #46

Open wagnerde opened 2 weeks ago

wagnerde commented 2 weeks ago

Datamapplot is an incredible package and I would love to use this for interactive exploration of single cell RNA seq datasets. However, for scRNAseq data, the ability to interact with additional (non-categorical) features is important. If the user were able to dynamically overlay alternative color mappings onto the data points (e.g. expression levels of individual genes, PCA scores, etc) this could add tremendous functionality. Datamapplot appears to be able to handle custom color mappings via "marker_color_array", but not interactively.

This may be outside the scope of your original vision for the tool, but could some guidance be provided on how one might incorporate such interactivity in the form of a pull-down menu /search bar ? Ideally one would be able to toggle between different sets of categorical and continuous color mappings while browsing the data.

Thank you Leland for building this beautiful plotting tool!

It is within scope, and is actually on my TODO list, but I haven't had the time to sit down and implement it properly. You can consider it one of the features I expect to have for the next major release however.
