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
