[ncl-talk] Density Scatter Plot

[MELISSA KAZEMI RAD]

Hi Rick,

I don't have any problem  plotting the scatter plot or changing the
translucency of the points. However, it doesn't have the desired visual
effect that I want, plus I am asked to overlay a heatmap contour plot of
the density of the point by journal reviewer, and that's what I couldn't
figure out how to do.

 I appreciate your help.
