Scales axis as with latitude in the Mercator projection. Adapted from this example. The scale function is as follows.\[y = \ln(\tan(\pi x/180) + \sec(\pi x/180))\]
The inverse scale function is as follows.\[x = 180\arctan(\sinh(y))/\pi\]
thresh (float, optional) – Threshold between 0 and 90, used to constrain axis limits between
The registered scale name.
limit_range_for_scale(vmin, vmax, minpos)
Returns the range vmin and vmax limited to some range within +/-90 degrees (exclusive).
