Hello,
The use of the TLatex class crashes ROOT. This happens even when trying to
execute the tutorial macro latex.C. I am using ROOT v2.23 on a Linux box (Suse
6.2, kernel 2.2.10), compiled with g++ 2.95.1. Is this a known problem that has
been fixed in later versions, or is there something wrong with my installation?
The only error message I get is:
*** Break *** segmentation violation
Also, TF1 seems to have problems drawing line styles other than solid when
the drawing area is small. E.g., the following macro produces identical plots
on both pads, whereas the second one should have a dot-dashed line
(incidentally, the documentation on TAttLine says that 3 gives a dot-dashed
line while 4 is a dotted one, which seems to be backwards from what I get).
Manually enlarging the second pad does make the line dot-dashed. These
problems persist in the Postscript output.
{
gROOT->Reset();
TCanvas *c1 =new TCanvas("c1", "Example", 200, 10, 1000, 500);
c1->Divide(2, 1, 0.05, 0.05, 0);
c1->cd(1);
TF1 *f1 = new TF1("f1", "sqrt(4*x)", 1, 8);
f1->Draw();
c1->cd(2);
TF1 *f2 = new TF1("f2", "sqrt(4*x)", 1, 8);
f2->SetLineStyle(4);
f2->Draw();
}
Regards,
Gora
