    I’ve been captivated by using the circular heatmap to visualize data, and Dex makes this so easy to do. Thank you!.

    I know it can do everything I want it to do as I’ve tried it out on a limited dataset. But I can’t quite get the colours syntax right to quantize/quantile/Identity/threshold display as I want them. My data range is from 0 to 11 in steps of 1 and I’ve tried entering “Silver,Orange,Green,SkyBlue,Blue,Salmon,MediumPurple,Sienna,Gold,Thistle,Olive,White” in the Options:Color Range field which almost works for Quantize and Quantile in that I get most of these displayed, but not quite.

    Help wouild be most appreciated.

      Thanks for the kind words!

      Maybe the data doesn’t fall within categories which map to each and every color? What version of Dex are you using? Also, email your data to and I’ll load it myself and take a look when I get a chance.
