Comment(by rlm):
All graphs used to plot as square plots, whether you wanted them to or
not. This would stretch any plot into a square, so if the relative
distances were larger in one dimension than in the other, this would not
show in the plot.
The following adjustment seems to improve the situation a bit, but I'm
really not sure what the "right" fix is here.
