Code:
ssc install heatplot
Code:
ssc install palettes, replace
Code:
ssc install colrspace, replace
I installed(reinstalled) the above packages to my Stata 17 (all updated) and run heatplot.
But, it comes up with the following error message and I couldn't have graphs.

Code:
function drop() not declared in class ColrSpace
(120 lines skipped)
Is there any solution for it?

I somehow managed this error by re-installing gr0075.pkg but once I run the graph combine syntax, the above error message appeared again.
