[ncl-talk] Density Scatter Plot

[Rick Brownrigg]

Hi Melissa,

You might try making the markers somewhat translucent to reduce their
overall visual impact.See the resource gsMarkerOpacityF at:

http://ncl.ucar.edu/Document/Graphics/Resources/gs.shtml

I might start with a value of 0.5 and decrease or increase to get the right
effect.

Hope that helps...
Rick
