num_contours	(int) The number of different colour levels to plot
contour_spacing	(int) How closely spaced the colour levels are

Methods

plot_colormap(x, y, z, num_contours=5, contour_spacing_dB=5)

Plot x, y and z on a colourmap, with colour intervals defined by num_contours at contour_spacing_dB intervals.
