Detailed Description

A transform that performs the Hammer-Aitoff projection.

A transform that performs the Hammer-Aitoff map projection. This map projection is an equal-area projection which displays the world on an ellipse. "Equal-area" means equal-areas on the globe are equal areas on the two dimension projection. If this transforms were used with an XY Plot containing the boundaries of the continents, it might look like image below.

Requests:: Cross hairs could follow the transform.
