It draws a Plot plt (see 'plot' function) in the given XWindow< +eop> +win, and on the given XScreen and XDisplay scn and dis, drawing the lines in<eo +p> +the foreground color.

The first vector (a) specifies the upper left corner<e +op> +of the bounding box. The next two vectors specify the bounding box itself,<eop +> +with respect to the first vector. This allows for non-rectangular bounding<eop +> +boxes.
