- class SineLatitudeScale[source]¶
Axis scale that is linear in the sine transformation of x. The axis limits are constrained to fall between
+90degrees. The scale function is as follows:\[y = \sin(\pi x/180)\]
The inverse scale function is as follows:\[x = 180\arcsin(y)/\pi\]
limit_range_for_scale(vmin, vmax, minpos)
Return the range vmin and vmax limited to within +/-90 degrees (inclusive).
