SetRangeCanvas()

void Helpers::SetRangeCanvas ( TCanvas *&  c, double  x_range_min, double  x_range_max, double  y_range_min = -999, double  y_range_max = -999  )

static

Set consistent x-axis and y-axis range for all TH1 histograms on a canvas.

Will only change the axes where min != max.

Parameters

c	Canvas Canvas
x_range_min	X-axis minimum
x_range_max	X-axis maximum
y_range_min	Y-axis minimum
y_range_max	Y-axis maximum

Definition at line 59 of file Helpers.cc.

ShiftTH1F()

void Helpers::ShiftTH1F ( TH1F *&  his, int  shift_bins = 0  )

static

Shift a histogram in x.

The histogram will be cycled, so bins at the end will be attached at the front and vice versa

Parameters

his	Histogram to be shifted
shift_bins	Number of bins in x to shift by

Definition at line 157 of file Helpers.cc.

SplitCanvas()

void Helpers::SplitCanvas ( TCanvas *&  c, vector< int >  active_channels, vector< int >  plot_active_channels  )

static

Helper to split canvas according to the number of channels to be plotted.

Parameters

c	Canvas to be split
active_channels	All channels available in the data
plot_active_channels	The channels from the data that should be plotted
