The mrlib/plot library provides a simple tool for plotting data values to a device context.
This is an old library, kept only for compatibility. You will undoubtedly want to use the plot library instead, which offers many more features and is actively maintained.
The points field contains the data values to plot, and connected? indicates whether the points are connected by a line. The pen field provides a pen for plotting points/lines. The remaining fields determine the plotting area within a drawing context.

Configures a plot. The grid? field determines whether to draw a grid at axis markings, and the x-axis-marking and y-axis-marking lists supply locations for marks on each axis. The other fields are self-explanatory.
