set-plot-pen-mode number
Sets the mode the current plot pen draws in to number. The allowed plot pen modes are:
- 0 (line mode) the plot pen draws a line connecting two points together.
- 1 (bar mode): the plot pen draws a bar of width plot-pen-interval with the point plotted as the upper (or lower, if you are plotting a negative number) left corner of the bar.
- 2 (point mode): the plot pen draws a point at the point plotted. Points are not connected.
The default mode for new pens is 0 (line mode).
This command will produce a runtime error if either the current plot or the current pen has not been set.
