Is there a way to show legend on tsne embedding plot?

[jingpingQ]

Hi there,

Thanks for your excellent work! I have three questions and hopefully you could help me out.

1.I was wondering if there is a input parameter of the function show.velocity.on.embedding.cor() in R that could add legend/title of the output figures rather than manually build it through plot() components?

2. Regarding for the differential expression and bio-marker/cell-marker analysis, do you have any suggestions? I was having a hard time to biologically interpret those clusters. The pagoda2 differential expression function did not have output for some of the clusters, and their heatmaps looks terrible...

3. Is there a way to plot only one targeted cluster's velocity on the figure? I tried it by changing the untargeted clusters' current and projected column in the expression matrix (in rvel.cd) to the same value, but it did not success.

Thanks again.

Best.

Hi, I also also to add legend to the velocity plot. Have you figured it out? Also, could you let me know how do you "manually build it through plot() components?" Thanks a lot, Yanwen
