Polar-Graph
Select at least one pair of XY columns. When using Polar theta(X) r(Y) to plot a graph, X represents the Angular (Units are in degrees) and Y is the Radius, and when using Polar r(X) theta(Y), X is the Radius and Y represents the Angular (Units are in degrees).
Take Polar theta(X) r(Y) for example.
POLAR.OTP for Polar theta(X) r(Y).
POLARXRYTHETA.OTP for Polar r(X) theta(Y).
(All above are installed to the Origin program folder).
