Hi I am trying to draw to Tvectors on the same plot with:
TVectorD * a = new TVectorD(4);
TVectorD * b = new TVectorD(4);
for( Int_t i=0; i< 4; i++)
b(i)=( (Double_t) i ) / 3;
But I keep ending up with a plot with only one histogram;
Also once i get them on the same plot how do i change the color of the lines?
Thanks for the help
