Hi,
I would like Draw more graphs in differents windows.
I created a class, and in this class I have
a member called "Draw".
It well runs.
But I have a problem: if I call this member for two different
objects, only the first one runs.
void MyClass::Draw()
{
// double *d contains my values
// n is the number of these values
double* x;
TGraph *gr;
int i;
TApplication* theApp;
TCanvas *c ;
double dd=0
TROOT simple("simple","Test of histogramming and I/O");
theApp = new TApplication("",&dd,NULL);
c = new TCanvas("c", "DEMO", 200,10,600,400);
x= (double*)calloc(n,sizeof(double));
for(i=0;i<n;i++) x[i]=i;
gr=new TGraph(n,x,d);
gr->Draw("AC.");
c->Update();
theApp->Run();
}
Example:
int main(){
MyClass c1,c2;
/*elaboration of c1 and c2*/
c1.Draw();
c2.Draw();
}
..but I can see only the c1 draw!!!
Thank you,
Giulio Ballardin
