Simple X-Y scatter plot

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”


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


without “a” the axis will not be drawn.
