Jeff, No the example doesn't show that line
If I reduce the amount of data, the border will be on every side of the plot I'll show you an orthographic plot with no maskinf tomorrow and you will see the problem easily, it wraps in a white line along the 0° meridian and a white circle in the pole I think it's the imshow layer that is not totally transparent on the map background.. I tried every trick I could for example to put some zero-valued points on each corner to make imshow interpolate correctly the sides, but that doesn't make any difference >De Pauw Antoine wrote: >> Jeff, >> >> Yes they disappear, and they fluctuate with the interpolation method used >> >> For example, nearest interpolation don't show the line >> >> Also, if I reduce the grid resolution, the line is thicker, and if I use a >> masked array to get rid of undesired values, the border shows really >> strongly >> >> Here's an example everyone will see: >> >> http://img225.imageshack.us/img225/2671/testfigep2.png >> >> (everything except the clouds is noise) >> >> Antoine De Pauw >> Collaborateur de recherches, Informatique - Research collaborator, IT >> Laboratoire de chimie quantique et photophysique - Quantum chemistry and >> photophysics laboratory >> Université Libre de Bruxelles - ULB >> > >Antoine: Sorry to seem dense, but I don't see anything wrong with that >plot.
