Scales axis to be linear in the sine of x in degrees. The scale function is as follows.\[y = \sin(\pi x/180)\]
The inverse scale function is as follows.\[x = 180\arcsin(y)/\pi\]
Construct a new scale.
The following note is for scale implementors.
The registered scale name.
limit_range_for_scale(vmin, vmax, minpos)
Returns the range vmin and vmax limited to some range within +/-90 degrees (inclusive).
