mollview command not returning plot image

I'm new to healpy and I'm trying to plot the following in iPython27:

import numpy as np
import healpy as hp

NSIDE = 32
m=np.arange(hp.nside2npix(NSIDE))
hp.mollview(m, title="Mollview image RING")

This does not return an image as I was expecting. What could be the problem?

Solution

  • You need to setup IPython to display matplotlib plots.

    If you are using IPython console

    %matplotlib

    If IPython notebook

    %matplotlib inline
