Hi I'm running into a problem using the mollweide projection, with the following simplified code, my actual code doesn't use random data for values but this is a clearer example to the problem I'm experiencing:
lon = numpy.arange(0, 361, 1) lat = numpy.arange(-90, 91, 1) x, y = numpy.meshgrid(lon, lat) values = numpy.random.random((181, 361)) map = basemap.Basemap(projection='moll', lon_0=0, resolution='c') map.drawcoastlines() map.drawcountries() map.drawmapboundary() map.drawmeridians(numpy.arange(0,360,30)) map.drawparallels(numpy.arange(-90,90,30)) X, Y = map(x, y) map.contourf(X, Y, values) I get the following error: WARNING: x coordinate not montonically increasing - contour plot may not be what you expect. If it looks odd, your can either adjust the map projection region to be consistent with your data, or (if your data is on a global lat/lon grid) use the shiftgrid function to adjust the data to be consistent with the map projection region (see examples/contour_demo.py). And the resulting map is incorrect due to the horizontal trends, see http://tier2.ihepa.ufl.edu/~ram/files/moll.jpg but if I use the orthographic projection ie: map = basemap.Basemap(projection='ortho', lat_0=-20, lon_0=-30, resolution='c') Then there are no errors, and the map is displayed as expected, see http://tier2.ihepa.ufl.edu/~ram/files/ortho.jpg I am unsure as to why I am receiving this error for the mollweide projection, as my coordinate grid is covering the entire surface. I am clearly doing something wring here but I don't know what - does anyone know what is causing this issue?
