Creates a ROOT density plot for one or all ROOT tree(s).
1 | root.density(x, treename = "*", logbase = "log2", canvasname = "DensityPlot", save.as = "", w = 540, h = 540)
|
x |
object of class |
treename |
name of tree, must be present in |
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. |
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.
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”.
