Re: Colorize markers from gsn_polymarker() with colormap

Hi Akio,

    I'm not sure if there is a way to use the color map automatically in
this case, but based on the "station_2.ncl" example, I had produced
colored markers with a colorbar. Attached is the script and its product.
Hope that helps.

    Cheers,
    deniz
