bool SetRealAspectRatio	(	TCanvas *const	c,
		const Int_t	axis = 1
	)

Function to resize a canvas so that a 2D histogram or TGraph / TGraph2D are shown in real aspect ratio.

Parameters

c	pointer to a TCanvas
axis	1 for resizing horizontally (x-axis) in order to get real aspect ratio, 2 for the resizing vertically (y-axis)

Returns

false if error is encountered, true otherwise

Note

For defining the concept real aspect ratio, it is assumed that x and y axes are in same units, e.g. both in MeV or both in ns

You can resize either the the width of the canvas or the height, but not both at the same time

Resize the canvas before calling this function, if you want a larger height or width of reference if you call with parameter axis= 1 or 2, respectively

Call this function AFTER drawing AND zooming (SetUserRange) your TGraph or Histogram, otherwise it cannot infer your actual axes lengths

This function ensures that the TFrame has a real aspect ratio, this does not mean that the full pad (i.e. the canvas or png output) including margins has exactly the same ratio

This function does not work if canvas is divided in several subpads
