What inspired this wish list request?
When using Multivariate platform and using "Color map on Correlations" and any other of the non-parametric color map on correlation (Spearman, Kendall or Hoeffding's D), the colors in the scale are reversed :
- For parametric color map, by default positive correlations are in red, negative ones in blue :
- For non-parametric color maps, by default positive correlations are in blue, negative ones in red (reversed color scale) :
What is the improvement you would like to see?
I would prefer having the same color scale/code for both type of correlation map : red for positive correlations, blue for negative ones. The colors difference between the two type of correlation maps can be misleading.
Why is this idea important? This issue should not be a big problem to fix, and would enable to have consistent color scales for correlations by default for all users. It would avoid any manual reformatting (or JSL scripting).
This problem is also highlighted when reading the JMP help : Multivariate Platform Options (jmp.com), where both color maps should have the same color scales : "on a scale from blue (+1) to red (-1)".
