Plot shape

plot_shape

Usage: plot shape x1 y1 x2 y2 x3 y3 x4 y4 ... (normal mode)

      plot shape [[x] y1...]                             (list mode)

Normal mode: The command draws a shape enclosed by a Bezier spline curve defined by the given points. The total number of points must be 3n, with integer n0.

List mode: The command draws shapes enclosed by Bezier spline curves through the points of the given vector expressions x, y1,... If no vector expressions are specified, splines are drawn through the points of all list columns. If the x-expression is omitted (i.e. if only a single expression, y1, is given), the x-coordinates are taken from the x-column of the list. The number of list points must be 3n, with integer n0.
