I have somewhat of a complicated problem involving trying to generate a
certain kind of contour plot. We have data that has been taken over the
past five years and would like to display all of the data in a contour
plot format with a time scale of only one year. In other words, we would
like to display the data from, say, Jan. 22 of all five years at the same
location on the time axis of he contour plot. We assumed that if we gave
IDL more than one z value for any given (x,y) point, it would do some
kind of averaging, smoothing or some other kind of trickery to arrive at
a single value for the contour(or SHADE_SURF, or any other kind of 3D
displaying method). If we try just giving the CONTOUR procedure more
than one z value for each (x, y) point, however, it simply displays two
contour plots superimposed on top of one another.
The alternative, of course, is for us to do some kind of external
averaging or smoothing before we pass the data off to CONTOUR, but we
don't want to have to do this if it is not needed. Any assistance on
this subject would be greatly appreciated.
