Polar Surfaces? [message #39617]

Hi, I have a huge amount of data that I'm working with and need to
plot and was hoping that someone could help me with.

The data has three coordinates - radius, polar angle, and time. I
want to create a circular image and then to create an MPEG out of the
different frames (imagine a moving satellite picture of the Earth...).
I did this by using "POLAR_SURFACE" and interpolating between the
data points. However, the problem is that I can't get a smooth outer
circle. IDL is taking the points with the largest radius and
connecting the dots to create the outline of my surface. Thus, I end
up with jagged edges and a misshapen diagram. Does anyone know what I
can do to make the interpolation spread throughout a larger circle
that would encompass the entire previous shape? Any help would be
greatly appreciated.

Thanks,
Jeff
