Hello
I have this idlgrcontour object that are missing quite a few of its
contours. I am trying to contour the contents of a 200x200 array using 60
contour levels, however, only the first 9 contours show up. If I ask for
120 contours it will show the first 19 etc. Hence, it looks to me that it
is the lower values it refuses to draw.
The max and min values of the data are -0.0222723 and -5.27345, and the
idlgrcontour object knows about this (I can read those values out using
getproperty). Idlgrcontour found those values by itself, so
apparently it knows about the entire array. Also, I can read out the
entire array and get the correct array out.
The viewplane_rect has the correct size. The contours are cut
off in the middle of the window.
The funny thing is that the contours can be drawn nicely using direct
graphics, so I know the data is correct.
Also, if I divide the entire dataarray with 10, idlgrcontour is capable of
drawing all the contours.
I put the two plots here:
http://www.fys.ku.dk/~staff/idl/
if you want to see how it looks. They should both have been with 60
contours, and they should have looked the same.
Any suggestions to what is going wrong?
Thanks,
Jan
PS: remove NOSPAM from my email address to get the correct one.
