Good morning everybody,
I have a problem with the CONTOUR routine and I need some experts help!
I have a 2-D data array with missing values marked as -1.0e20. Doing a
contour plot I use the MIN_VALUE keyword and set it to -1.0e10. The
result is that contours stop, once they reach the missing data region.
This is how it should be. As a next step I want to get the paths of the
contours (with PATH_XY and PATH_INFO) and there starts the problem:
Using the MIN_VALUE keyword seems to eliminate all contours that touch
the missing data region. If I omit the MIN_VALUE keyword, the contours
run along the missing data region and connect with contours of the same
value somewhere else. This is though what I need to avoid.
Thus the question is: Is there a way to obtain the paths data exactly as
they are plotted in the first described case?
I hope this wasn't too confusing to understand and if you had similar
problems and know an answer, please let me know!!!
Thanks a lot,
Haje
