This notebook demonstrates how to generate a simple 3-dimensional plot of the data in an SHGrid class instance.
%matplotlib inline
from pyshtools import SHCoeffs
lmax = 70
coeffs = SHCoeffs.from_zeros(lmax)
coeffs.set_coeffs(values=[1], ls=[10], ms=[0])
grid = coeffs.expand('GLQ')
grid.plot_3dsphere(elevation=20, azimuth=30);
