Re: scatter plot with multiple colored markers

Hi Debasish,

Each element in xyMarkerColors resource applies to a group of markers, and not individual values in a 1D array.
You need to have a 2D array, where the leftmost dimension represents a particular grouping of markers with
one color, and the rightmost dimension is the number of markers.

In your case, you have 6 different colors, so what you really want is a 6 x n array that you pass to gsn_csm_xy.
If you have a different number of markers for each color, then "n" will have to represent the largest possible
number of markers associated with one color.

See the attached sample script.
