Additional plotting objects

General

To plot additional user defined objects into your plot you first need to create the plot:

test.create_plot()

Then you can get the axis of the plot where you want to add something:

test.Get_axis1()

The you can add your preferred custom object to this axis. At the moment this custom plotter are collected in the object_plotting.py file in the PlotLib repository. Therefore it is useful to include this file in your plotter if you want to use the functionality:

from object_plotting import *

Cut markers

As a first example some functions to draw cut markers into your plot are included (draw a line at the cut value and an arrow indicating the cut direction). The first function draws an upper cut:

plot_upper_cuts(test.Get_axis1(),0.1)

The second one a lower cut:

plot_lower_cuts(test.Get_axis1(),0.1, -0.2)

And of course you can have them combined (for this functionality you could also just call both previous functions):

plot_both_cuts(test.Get_axis1(),0.1, -0.2, include = False)

An example plot with upper and lower cut would then look like this example

Gauss fit

If you want to also fit a gaussian and plot it into your figure you can use this function:

plot_gauss_fit(test.Get_axis1(), bghists.getHistList()[0], xmin = -0.5, xmax = 0.5)

Which gets the axis where the plot should appear, the histogram which will be used for the fit and the fitting range. The result should then look like this example
