LogNorm(vmin=None, vmax=None, clip=False) [source] # Bases: Normalize Normalize a given value to the 0-1 range on a log scale. Matplotlib’s colormap (cmap) system is much richer than “just pick a color scheme. I have a logarithmic imshow figure, and when the colorbar is created, its axis labels and ticks are logarithmic, but because of the short range (0-50) of the values, I am using pyplot (Julia version of matplotlib) to do plotting in Julia.
