1 . Why does this work to plot the 2 lines on the same graph? It seems
like whenever I want to overlay two lines, I have to do
in order to get the second graph on top of the first.
2. Is there any way to scroll through a history of graphs that have
appeared. Often I'm snooping through data and want to compare one graph
with the one before, and it is puzzling that I can't find a way.
