Is the only way to do it using matplotlib.An ellipse is a curve that is the locus of all points in the plane the sum of whose distances and from two fixed points and (the foci) separated by a distance of is a given positive constant (Hilbert and .In detail: this is an ellipse quadrant with parameters a = 5, b = 1: And this is a plot of the length of the arc subtended by an infinitesimal change in the angle, at each angle: The x axis is the angle, in radians, and the y axis is the length of the arc that would be subtended by a change in angle of 1 radian. Be careful: a and b are from the center outwards (not all the way across). (Note: for a circle, a and b are equal to the radius, and you get π × r × r = πr2, which is right!)
