How to plot using two variables as x and y axes?

[Vikas_Raj]

Dear experts how to set custom x and y axes to plot multiple graphs?

basically, I want to plot something like this

Lambda->Draw("Pi_SVDdEdx:Pi_pSVD", " Pi_pSVD > 0 && Pi_pSVD <1") "

but, two plots data and mc on same canvas.

thank you!

ambda->Draw("Pi_SVDdEdx:Pi_pSVD", " Pi_pSVD > 0 && Pi_pSVD <1") "

but, two plots data and mc on same canvas.

Irt seems you are drawing a TTree. You ask for Pi_SVDdE versus Pi_pSVD.

What is mc ?

I intend to plot Lambda->Draw("Pi_SVDdEdx:Pi_pSVD", " Pi_pSVD > 0 && Pi_pSVD <1") from data & montecarlo, basically two different root files on same canvas.

Do the 2nd plot with option SAME:

Lambda->Draw("Pi_SVDdEdx:Pi_pSVD", " Pi_pSVD > 0 && Pi_pSVD <1", "SAME")
