Hi Rooters,

I'm trying to get a semi-log plot to show graphical data that 
varies over 12 orders of magnitue.  

eg.

  c1->SetLogy();
  gr = new TGraph(145,mtv,ptinv_dndpt);
  gr->Draw("AP");

when I make the plot the graph only shows data > 10^7.
The vectors mtv and ptinv_dndpt are filled correctly
with data that ranges in decades from 10^0 to 10^12.

any ideas are appreciated.

Sean
