Hi, I was trying to set the limits of the Y axis for a TGraphErrors plot (the macro is still under development), but I can set the Y axis limits. No problem with X axis limits. Maybe because I am plotting using the Time Format mode. I attach the macro. I am sure you have useful comments on what I am doing…

Thanks a lot in advance

regards

Example:

```
{
Int_t n=20;
Double_t x[n],y[n];
for (Int_t i=0; i < n; i++) {
x[i]=i*0.1;
y[i]=10*sin(x[i]+0.2);
}
TGraph *gr1 = new TGraph (n,x,y);
TAxis *axis = gr1->GetXaxis();
axis->SetLimits(0.,5.); // along X
gr1->GetHistogram()->SetMaximum(20.); // along
gr1->GetHistogram()->SetMinimum(-20.); // Y
gr1->Draw("AC*");
}
```
