Re: [Matplotlib-users] Basemap help, imshow, transform_scaler

Shoot, still getting the error discussed above:

ValueError: shape mismatch: objects cannot be broadcast to a single
shapeFile "c:\07_jfb\Programming\Python\mod_flexpart\plotPickle.py", line

  fp_plot(z);

  cs = m.contourf(x,y,zdat)
File "c:\Python25\Lib\site-packages\matplotlib\toolkits\basemap\basemap.py",
line 2439, in contourf
  mask = NX.logical_or(ma.getmaskarray(data),xymask)


What seems strange, is that after following your instructions:
nx = int((m.xmax-m.xmin)/20000.)+1; ny = int((m.ymax-m.ymin)/20000.)+1
zdat,x,y = m.transform_scalar(Zdat,lons,lats,nx,ny,returnxy=True)
lons, lats = N.meshgrid(lons, lats)
x, y = m(lons, lats) # map is the Basemap instance
cs = m.contourf(x,y,zdat)

The shape of my zdat no longer fits??
>>> print [N.shape(i) for i in [x,y,zdat]]
[(180, 360), (180, 360), (596, 596)]
