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

Description

Normal mode:
Draws a shape enclosed by a closed Bézier spline curve that is defined by the points (xi,yi). The total number of points must be 3n, with integer n.

List mode:
Draws shapes enclosed by Bézier spline curves through the points of the given vector expressions x, y1,... If no vector expressions are specified, shapes are drawn for 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 n.
