I'm probably not the first person to have this problem,
but I didn't recognize any of the archived messages as
pertaining to it.
I'm contouring a 20x20 point grid of data. The positive
contours look fine, but the negative ones are bulls' eyes
around the data points, up to 4 contours around each point.
The data *are* close enough together that when I set the
smoothing to be .001 the contours from different data points
cross each other! When I try a large smoothing (>10.0) the
contours turn in to polygons with the outer contours (all
having the same value) almost touching each other.
I called
CALL CPSETR('T2D',SMTH)
to do the smoothing.
Negative values, which are supposed to interpolate the data
before contouring it, did not help.
I've considered manually interpolating the data before contouring
it, but it seem like there should be better way within NCAR
Graphics.
Thanks,
Kevin Raeder
