Simple X-Y scatter plot

ROOT
1

Very simply:
How do I make a scatter plot with more than 1 value per x-coordinate?

I just want to be able to place points in a plane with x-y values, not being constrained to 1 x-value per y-value, OR vice versa.

A Thousand Thanks,

Simply create a TGraph object

TGraph *g = new TGraph(n,x,y); //where x , y are 2 arrays of n points and draw this graph with option “p”

g->Draw("p");

Do not forget the option “a” if your TGraph is plot on an empty pad, and if you need to plot the axis:

g->Draw("ap");

without “a” the axis will not be drawn.
