Normalise Y-Axis of IslandCounter #65

Closed AndrewEdmonds11 closed 10 years ago

AndrewEdmonds11 commented 10 years ago

In my notes from today's meeting I've written: "BU Island Lengths - Normalise y-axis". Looking at this plot, I can't remember why: hdq_islandlength_musc_cabu_normalised_trendplot

I thought it was because we were worried that drops in the muon beam might be showing up but I can't work it if this is the right plot.

It was the number of TPIs plot, not the length plot

jrquirk commented 10 years ago

The Y-Axis would need to be normalized to the muon rate, maybe not just the number of muons. If all the runs are the same length timewise it doesn't make a difference.

Maybe you meant for the UH length plots with the germanium which had different y-axes between normalised and un-normalised versions?

AndrewEdmonds11 commented 10 years ago

Yes, it was the number of TPIs. Thanks, John.

Ben, the problem you're talking about is issue #43, I think

So, to clarify, it's the y-axis of this trend plot (i.e. the x-axis of the individual run plot) that needs changing.

This one was quite difficult to do because there's not a simple Scale() function for the x-axis, so I had to go the round about way and fill in a new histogram with the scaled values. This means we now have three histograms, one with no normalisation, one with the y-axis normalised and one with both axes normalised.
