Hi,
I am having trouble drawing a function in a pad
with log axes in the case when the function
range is smaller than the defined axis range.
In the following macro, the defined function
is never drawn.
{
gROOT->Reset();
c1 = new TCanvas("c1","TF1 with log Axes",200,10,700,500);
c1->SetLogx();
c1->DrawFrame(1,0,100,1);
f = new TF1("f","1/x",5,80);
f->Draw("same");
}
Note that if I do not use log axes, or if I
define the function range to be larger than
the frame, the function is properly drawn
within the frame. I discovered this in
try to fit a TGraph with a function with
a range smaller that the data points within
the TGraph. Here again, the fitted function
is never drawn when the TGraph is drawn.
Cheers,
Glenn
