# SineLatitudeScale¶

class SineLatitudeScale[source]

Bases: _Scale, ScaleBase

Axis scale that is linear in the sine transformation of x. The axis limits are constrained to fall between -90 and +90 degrees. The scale function is as follows:

$y = \sin(\pi x/180)$

The inverse scale function is as follows:

$x = 180\arcsin(y)/\pi$

Methods Summary

 limit_range_for_scale(vmin, vmax, minpos) Return the range vmin and vmax limited to within +/-90 degrees (inclusive).
