PolyMarkers Question

Hi,

Can one enable coloring of polymarkers with NCL, just like you would for
contouring, i.e. different colors for chosen bins. I looked through the
documentation section of polymarkers, but didnt find this capability.

Please see a plot at the link below, that was produced from a different
software. The diamonds on these plots indicate not only the locations of
observed stations, but also the magnitude of the observed values, i.e.
the diamonds are colored using the same color-bin that are used for the
tile-plot (represents the modeled data).

This type of plot helps in comparing model predictions compared to
observations on the same plot.

Thanks.

Sarav Arunachalam
