(2,3) (1,1); (-1,-1) (-3,2)
By prefixing one of the points by a P, FX Graph will interpret all of the points as being in polar form, (r, q). When entering points in polar form, you need to enter the angle in the currently selected angle type.
P(6,pi/4) (3,3pi/4) - angle set to Radians
Constants
Points can contain constants which are discussed later in this manual. You can enter a point of (-3a,b) for example.
