dear rooters,
if i want to fit histogram *h1* with several *"gaus"* functions, i can carry out the next procedure:
...............
TMarker *m;
Double_t limits[100];
int num = 5;
....................
for(int j = 0; j < num*2; j++) {
m = (TMarker*)gPad->WaitPrimitive("TMarker","Marker");
*limits*[j] = m -> GetX();
m -> Delete();
}
................... g1 = new TF1("g1","gaus",limits[0],limits[1]); g2 = new TF1("g2","gaus",limits[2],limits[3]); g3 = new TF1("g3","gaus",limits[4],limits[5]);g4 = new TF1("g4","gaus",limits[6],limits[7]); g5 = new TF1("g5","gaus",limits[8],limits[9]);
h1 -> Fit("g1","RQ+"); h1 -> Fit("g2","RQ+"); h1 -> Fit("g3","RQ+"); h1 -> Fit("g4","RQ+"); h1 -> Fit("g5","RQ+");
h1 -> Draw();
....................
i remember, somewhere in tutorials i saw how to make the same think in one loop, but unfortunatly i cannot find it.
thank you,
boris.
