root.density: ROOT Density Plot

Description

Creates a ROOT density plot for one or all ROOT tree(s).

Usage

root.density(x, treename = "*", logbase = "log2", canvasname = "DensityPlot", save.as = "", w = 540, h = 540)

Arguments

x

object of class DataTreeSet or ExprTreeSet.

treename

name of tree, must be present in rootfile of object x.

logbase

usually “log2”, or “0”, determines if leaf data should be converted to log.

canvasname

name of ROOT canvas

save.as

graphics type 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 density plot for one or all tree(s) 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.
