Hi,
(Well ... you asked for it :-)
The ROOT is 3.02/07 RH6.2/i386 with egcs-1.1.2.

Observe :
Float_t x[3] = {1,2,3}
Float_t y[3] = {10,20,30}
TGraph *g1 = new TGraph(3,x,y)
TGraph *g2 = new TGraph(3,x,y)
g1->SetTitle("XabgdeY")
g2->SetTitle("X#alpha#beta#gamma#delta#epsilonY")
new TCanvas()
g1->Draw("AL")
new TCanvas()
g2->Draw("AL")
See the "title" TPaveText in both canvases (and the fLongest data member).
Try the same with a TMultiGraph instead of TGraph (should be the same
problem).
> (...) MyGraph->GetXaxis() will return 0.
That would be very nice ... however ...
Observe :
Float_t x[3] = {1,2,3}
Float_t y[3] = {10,20,30}
TGraph *g1 = new TGraph(3,x,y)
g1->Draw()
g1->GetXaxis() // *** Break *** segmentation violation
or :
Float_t x[3] = {1,2,3}
Float_t y1[3] = {10,20,30}
Float_t y2[3] = {11,22,33}
TGraph *g1 = new TGraph(3,x,y1)
TGraph *g2 = new TGraph(3,x,y2)
TMultiGraph *mg = new TMultiGraph("MMG", "My MultiGraph")
mg->Add(g1)
mg->Add(g2)
mg->Draw()
mg->GetXaxis() // *** Break *** segmentation violation
mg->Draw("L")
mg->GetXaxis() // *** Break *** segmentation violation
g1->GetXaxis() // *** Break *** segmentation violation
mg->Draw("A")
mg->GetXaxis() // NO segmentation fault any more
g1->GetXaxis() // *** Break *** segmentation violation
If you want to have more fun ... try the above sequence without these two
lines "mg->Add(...)" (leave the TMultiGraph mg "completely empty") ...
How about my problem that when I interactively zoom one of pads (x- or
y-axis), all the others are also affected. No simple way to make their
axises "independent" ?
Thanks in advance,
Best regards,
Jacek.
