Well, your patch seems quite good concerning scientific plots at least.
I am not sure it would be the same thing for other plots, as bar plots
in statistics. As a scientist (chemist), I would like it adopted, but I
am not sure it would be a good thing to impose this to everybody. What
would be most interesting is a configurable default behavior.
