Hi,

You probably missing the creation of a TApplication object (see
$ROOTSYS/test/stress.cxx for an example).

You are also probably missing a way to stop the program after 
the drawing and before the end of the main.

Cheers,
Philippe.

Hello,

  I'm building a program in which I want to plot a graph and fit it, and 
I would like to see the fit in a canvas for example, but I tried
to create the canvas and then to draw the graph but nothing happens, the 
program ends. I think it could be because of the libraries I link
or the includes I need, but I don't know.

 I link with:

-lCore -lCint -lHist -lGraf -lGraf3d -lGpad -lTree -lRint -lPostscript 
-lMatrix -lPhysics -lpthread

and I include:

#include <TROOT.h>
#include <TChain.h>
#include <TFile.h>
#include <TGraph.h>
#include <TH1F.h>
#include <TH2F.h>
#include <TH2.h>
#include <TStyle.h>
#include <TCanvas.h>
#include <TF1.h>

Many thanks

    Belen.
