The mrlib/plot library provides a simple tool for plotting data values to a device context.

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.

Draws the data-sets in data into the given dc. Uses drawing-context coordinates in data-sets that will accommodate all of the data sets.
