ROOT M vs A Plot

Description

Creates a ROOT M vs A plot for a ROOT tree.

Usage

root.mvaplot(x, treename1 = character(0), treename2 = character(0),logbase = "log2", option = "P", canvasname = "MvAPlot", save.as = "", w = 540, h = 540)

Arguments

x object of class ExprTreeSet or DataTreeSet.
treename1 name of first tree, must be present in rootfile of object x.
treename2 name of second tree, must be present in rootfile of object x.
logbase usually “log2”, or “0”, determines if leaf data should be converted to log.
option ROOT TGraph::PaintGraph option, usually one of “P”, “*”.
canvasname name of ROOT canvas
save.as gaphics tye for saving canvas, one of “ps”, “eps”, “pdf”, “jpg”, “gif”, “png”, “tiff”
w the width of the canvas in pixels.
h the height of the canvas in pixels.

Details

Creates a ROOT M vs A plot for trees treename1 and treename2 present in rootfile.

By selecting menu “File->Save->canvasname.xxx” you can save the figure as e.g. *gif, *.jpg, *.pdf, *.ps or even as C++ macro.

Alternatively, you can save the plot by setting save.as. However, this will close the canvas immediately after opening it.

Note

Always select menu item “Quit ROOT” from menu “File” to close the ROOT canvas, otherwise you are in the CINT C/C++ interpreter from ROOT. To exit CINT, you need to type “.q”.
