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.

ROOT TGraph::PaintGraph option, usually one of “P”, “*”.

canvasname

name of ROOT canvas

save.as

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.
