[ncl-talk] gsnXYBarChartColors request

[Rick Brownrigg]

Hi Alan,

Yes, I see what you mean here.  There is ambiguity on how to interpret the
dimensionality of the colors array -- should it be construed as RGBa
color-specs, or is it an array-of-arrays of colors for multiple y-curves?
I'll file a ticket on this one.

I unfortunately don't have a good work-around for you... :-/
