Hi Couet,
Your example is not correct. In the full code I would like to see the first plot after that change some parameters and draw the second plot. Your example equals to
TMultiGraph *pMG = new TMultiGraph();
TGraph *pG1 = new TGraph(n,x,y1);
TGraph *pG1 = new TGraph(n,x,y2);
pMG->Add(pG1);
pMG->Add(pG2);
pMG->Draw(“LA”);
and it is a usual using of TMultiGraph class.
Thus it is not an answer.
More simple try to use the next commands wth my class
.L a.cpp
A a
a.d1(0)
//== here I see the first plot
a.d1(10)
//== and more interesting
a.d1(2) //== you will see part of the second plot
Best regards,
Andrey
