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. -----Original Message----- From: email@example.com [mailto:firstname.lastname@example.org]On Behalf Of Belen Salvachua Ferrando Sent: Tuesday, April 13, 2004 11:58 AM To: email@example.com Subject: [ROOT] see a graph in a canvas with a comnpiled application 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.
