 Calculate should save the equation in the history sidebar used to generate
 a plot along with the generated plot.

 The plot() equation used is saved in the history available via the up/down
 arrow keys in the formula entry area; but it would be nice to show it
 immediately above the plot like non-plotting equations are above their
 results.

 Seen in OLPC 12.1.0 os11/Calculate-40.
