Dear All, I used to use griddata in order to make my contourmaps. However, after I updated my Python from 2.6 to 2.7 griddata is not working anymore.
I tried some workarounds but no success. The countourmap that I produced before is here. http://dl.dropbox.com/u/17983476/matplotlib/contour_dT_workingbefore.png After the Python 2.7 update, it turns to the following. http://dl.dropbox.com/u/17983476/matplotlib/contour_dT_broken.png Here is the datafile. http://dl.dropbox.com/u/17983476/matplotlib/contour_dT.dat And the associated python script (which is also below). http://dl.dropbox.com/u/17983476/matplotlib/contour_dT.py The code that I was using before is here. I had to comment out #import griddata line because this is the only way that it continues. Is this a bug in griddata, or if there are new workarounds, I would be glad to know a new method to produce my contourplots again.
