[ncl-talk] How to change color bar for the second field using gsnHistogramCompare

[rK Aditya]

Dear Guilherme,

Thank you for the suggestion. I tried to activate gsnXYBarChart toTrue as
well, but  gsnXYBarChartColors2 or gsnXYBarChartColors are not valid
resources for this. I still could not change the color bar for the second
field.

Kindest regards,
-r/K-
