Hi All,

in my script I use the following code:

....
TDatime *T0;
T0 = new TDatime( date[0].Data() );
X[0] = T0->Convert();

TDatime *T;
for( Int_t i = 1; i < index; i++ ) {
  T = new TDatime(date[i].Data() );
  X[i] = T->Convert() - X[0];
}
...
h_pmt->GetXaxis()->SetTimeDisplay(1);
h_pmt->Draw();

to put a time on x-axis. The problem is the following, on x-axis the time is drawing in the format: day-hour-min, but I would like to have only minutes increasing with the time (for example: 0 30 60 90 min ... 300 330 min ...)

Can you help me to resolve this problem ?

Thanks in advance
