scRNA-seq heat map scale bar

[JUN YANG]

I am reaching out for an issue of scRNA-seq expression scale.

In particular, for the rhabdomyosarcoma, 

(https://proteinpaint.stjude.org/RMS-scrna-atlas-2020/tissue.html), I generated a multiple-gene heat map for several genes but the scale bar looked very weird and doesn’t make any sense (Please see attached screenshot). I wonder if you can help to fix it.

Thanks

Jun
