It is now invalid for linscale to be 0

vmax=maximum_scale_level,

# Setting "linthresh=minimum_log_level" makes its non-logarithmic
# data range equal to our 'zero band'.
# Setting "linscale=0" maps the whole zero band to the middle colour value
# (i.e. 0.5), which is the neutral point of a "diverging" style colormap.
# Setting "linscale=1" maps the whole zero band to the middle colour value
# (i.e., 0.5), which is the neutral point of a "diverging" style colormap.

# Create an Axes, specifying the map projection.
