The Canvas class.

A Canvas is an area mapped to a window directly under the control of the display manager. A ROOT session may have several canvases open at any given time.

A Canvas may be subdivided into independent graphical areas: the Pads. A canvas has a default pad which has the name of the canvas itself. An example of a Canvas layout is sketched in the picture below.

This canvas contains two pads named P1 and P2. Both Canvas, P1 and P2 can be moved, grown, shrunk using the normal rules of the Display manager.

Once objects have been drawn in a canvas, they can be edited/moved by pointing directly to them. The cursor shape is changed to suggest the type of action that one can do on this object. Clicking with the right mouse button on an object pops-up a contextmenu with a complete list of actions possible on this object.

A graphical editor may be started from the canvas "View" menu under the menu entry "Toolbar".

An interactive HELP is available by clicking on the HELP button at the top right of the canvas. It gives a short explanation about the canvas' menus.

A canvas may be automatically divided into pads via TPad::Divide.

At creation time, no matter if in interactive or batch mode, the canvas size defines the size of the canvas window (including the size of the window manager's decoration). To define precisely the graphics area size of a canvas in the interactive mode, the following four lines of code should be used:

{
   Double_t w = 600;
   Double_t h = 600;
   auto c = new TCanvas("c", "c", w, h);
   c->SetWindowSize(w + (w - c->GetWw()), h + (h - c->GetWh()));
}

and in the batch mode simply do:

c->SetCanvasSize(w,h);

If the canvas size this exceed the window size, scroll bars will be added to the canvas This allows to display very large canvases (even bigger than the screen size). The Following example shows how to proceed.

{
   auto c = new TCanvas("c","c");
   c->SetCanvasSize(1500, 1500);
   c->SetWindowSize(500, 500);
}

Returns: false if error is encountered, true otherwise

return c1

Definition: legend1.C:41

For defining the concept of 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 width of the canvas or the height, but not both at the same time
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 the canvas is divided in several subpads

void TCanvas::Size	(	Float_t	xsize = `0`,

Set the canvas scale in centimeters.

This information is used by PostScript to set the page size.

Parameters

[in]	xsize	size of the canvas in centimeters along X
[in]	ysize	size of the canvas in centimeters along Y

if xsize and ysize are not equal to 0, then the scale factors will be computed to keep the ratio ysize/xsize independently of the canvas size (parts of the physical canvas will be unused).

if xsize = 0 and ysize is not zero, then xsize will be computed to fit to the current canvas scale. If the canvas is resized, a new value for xsize will be recomputed. In this case the aspect ratio is not preserved.

if both xsize = 0 and ysize = 0, then the scaling is automatic. the largest dimension will be allocated a size of 20 centimeters.
