Not Python arrays, but numpy arrays.  The reason this is done is to save
space for huge data sets.  My assumption was that it is unusual to plot
values that vary only in the ninth decimal place.  And since there is a
workaround, it doesn't seem like a bad compromise.

But feel free to change it in your copy :-)
