plot.path_curve: Plot history curves.
Description
The default plot method is a line plot with step on the x axis and
value on the y axis. Each observation is drawn with a different line
line and the plot is facetted by variable. This is rather similar in
spirit to a parallel coordinates plot or Andrews curves.
