Setting the axis title via the right mouse button is one thing. But if I
have a TGraph object say "gr", the command
gr->GetHistogram->SetXTitle("X axis");
produces an error message:
illegal pointer to class object GetHistogram()
What is wrong here ? Using only "gr->GetHistogram();" works but has no
effect.
Is it possible to use an histogram instead of the graph. Can you make
fits using (x,y) pairs within a histogram or is it only possible to fit
one set of values that is spread equally over a discrete number of
channels (like in the tutorial-file multifit.C)? Any suggestions?
Oh, a last one. there is a howto about using Postscript. When I use this
and I try to change the size of the resulting picture via "Range(8,8);"
the code doesn't produce a picture that is 8 cm by 8 cm but a picture
that has stil the default size.
Any help is appreciated
bye,
Mats
P.S: Congratulations for "root", I really like it. Finally one can
create plots whithout spending hours with a "point an click" interface.
