ROOT::EnableImplicitMT(2); ROOT::RDataFrame d(160);
Create a trivial parabola
auto dd = d.Alias("x", "rdfentry_").Define("y", "x*x"); auto graph = dd.Graph("x", "y");
This tutorial is ran with multithreading enabled. the order in which points are inserted is not known, so to have a meaningful representation points are sorted.
graph->Sort(); auto c = new TCanvas(); graph->DrawClone("APL");
Draw all canvases
