The Draw method of the TTree class provides a neat way to interactively plot an Array leaf element against the entry numner, such as:
TTree->Draw(“Array:Entry$”); // to plot the first array element against entry number.
However, it would be even nicer to be able to normalize the plot by a chosen element of a chosen entry, e.g. using the first entry or first element. It would look something like:
and similarly, something like:
Is there a way to do what are described above interatively?
