WP on Z' samples should have the option to be based on ttbar

Thinking about this, I'd guess the easiest way is to just give the draw_vlines object the x values for that. Because connecting the two samples (calculating on the one and plotting the other) is not so trivial. Because these two samples are normally not plotted in the same plot. We could however, add a little helper function to draw_vlines where we can just give him the disc cut values and he automatically calculates the x_values for the given plot/sample.

Is this something which would work for you @samvanstroud?

@afroch do you mean to use draw_vlines to compute the cut values on ttbar, and then to manually pipe this info to the plotting script for Z'?

That is one option. Previously I handled this by allowing the taggers to specify their own WP cut values, and then use a helper script to define these. We could add this e.g. in the High Level API, e.g. something like:

Tagger(..., wp_cuts={70: 1.5})

Then the plotting script can just use the provided WP cut values for each tagger

The tools package now includes a handy script to calculate working points. We could use this in the solving of this issue
