Dear root'ers,

i have a problem with using the scan feature in the TMinuit class. SCAN uses
mnplot to display the output, but the output does not contain any points and
the labels on the x-axis are corrupted.

The program :
int main(void)
{
TROOT simple("simple","Example of creation of a tree");
TM *tm = new TM(3);
tm->SetFCN(fcnmin);
Double_t y[]= { 5,4,3,2,1,1.5,2,2.5,3,3.5 };
Double_t x[]= { 2,3,4,5,6,7 ,8,9 ,10,11 };
TString ch[]= { "a", "b", "c", "d", "e", "f", "g", "h", "i", "j" };
tm->mnplot(x,y,ch,9,80,20);
}

generates :

5.25 ..

4.75 ..

4.25 ..

3.75 ..

3.25 ..

2.75 ..

2.25 ..

1.75 ..

1.25 ..

0.75 ..
0.5 ..

1.8a
3.8a
5.8a
7.8a
9.8a
ONE COLUMN= 0.2 Overprint character is &

Ciao
Thomas
