Creates a ROOT profile plot for all trees treename="*" present in rootfile, or for
a subset of trees. In this case varlist must be the name of one tree leaf only;
for varlist=NULL leaf "fInten" will be used for class DataTreeSet and
leaf "fLevel" will be used for class ExprTreeSet. If treename is the name of one tree only then varlist can contain up to all leaves
of the tree, separated by colons, e.g. varlist="fLevel:fStdev".
For boxes=TRUE the profile plot draws box-and-whisker plots and can thus be considered the
equivalent of the usual boxplot.
A ROOT profile plot, i.e. a plot of parallel coordinates, is drawn in a TreeViewer, a
graphic user interface designed to handle ROOT trees. You can activate context menus
by right-clicking on items or inside the right panel.
The TreeViewer is explained in http://root.cern.ch/root/html/TTreeViewer.html.
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.
