Plot fktable x grid
Created by: Zaharid
The way I imagine it, one would have the existing PDF plots (e.g. the replica and the band ones), in exactly this basis to start with
with the draw method supplemented with the ability to plot ticks for the xgrid for a bunch of fktables.
Possible refinements include sizing the ticks based on some measure of contribution to the cross section (this would need some thought, e.g. is it scaled by the exp unc of different datapoints?) or the ability to change basis (which shouldn't be very hard but again would involve deciding how to deal with fractional ticks.).
