[ncl-talk] About the represent of minor large value in raster fill?

[Rick Brownrigg]

Hi Tao,

Do you know where this outlier occurs?  Its seems to me it is entirely
possible that it is getting drawn, but overwritten by subsequent,
overlapping points.  To test this, you might set your min bounds to
something like 200 rather than 40, and enlarge the marker size (via
gsMarkerSizeF resource).

If that's the case, I'm not sure what to suggest other than sort your data
smallest to largest, assuming you want to emphasize the larger values.

Hope that helps...
Rick
