[Rivet] plotting two different ratios on same plot

[Raghav Kunnawalkam Elayavalli]

Yeah i agree with both of you guys that modifying tex files (once you know where things end up, is pretty methodical to make the plots you want) is not the best way forward. I briefly looked at the yoda interface and maybe ill set this up when i get some free time. 
I also quite like the make-plot system for simple plots, since using it after being a root user for several years. 

Cheers
Raghav

There are also some functions in yoda.plotting which can help with converting YODA objects to number arrays that could be used as input to matplotlib -- feedback on those would be great, since I've not had time to finish designing/iterating that "new" plotting system.

But it is limited in functionality. I'd love to either replace it with a matplotlib-based system with equal-quality output (which I've failed to do so far) or to isolate the components into a library which can be used more programmatically. Being the ultimate back-burner project, progress on either route has been infinitely slow, but if others would be interested in making our plotting more flexible/powerful then let me know and maybe we can start a new branch for collaboratively developing that side of things.
