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

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?

Cheers
