Dear roottalk. I'm doing a program that use ROOT's ability to generate postscripts. Essentiailly, this program is called by cron in a machine with no X-window (no grafical interface). The postscripts are gererated from histos. So i do something like this: ... TFile *f; TH1F *histo; TCanvas *myc=new TCanvas("c","c",0,0,600,400); ... f = new TFile("servers_stats.root","RECREATE"); ... gStyle->SetOptStat(0); for (int i=0;i<nlines;i++) { Float_t size=0.0; TPostScript *ps = new TPostScript(name[i]+".ps",112); ... histo=new TH1F(name[i].Data(),"database server progression",3000,0,3000); histo->SetFillColor(4); histo->SetMaximum(2100000); int count=0; while(rs->Next()) { size = rs->GetFloat(1); histo->Fill(count,size); count++; } ... if (size>500000.0) myc->SetLogy(0); else myc->SetLogy(1); f->Write(); histo->Draw(); TF1 *max=new TF1("max","2100000",0,3000); max->SetLineColor(6); max->Draw("same"); TF1 *dangerous=new TF1("dangerous","1900000",0,3000); dangerous->SetLineColor(2); dangerous->Draw("same"); TLegend Legend(0.8, 0.2, 1.0, 0.4); Legend.SetHeader(name[i]+"Kb/hour:"); Legend.AddEntry(histo, "Growth Size", "f"); Legend.AddEntry(max, "Maximum File size", "f"); Legend.AddEntry(dangerous, "Dangerous size level", "f"); Legend.Draw(); myc->Update(); ps->Close(); ... Is there any way to this like "silent"; in a way that not need the X-window?. There is, probably, a method to do that. I hope. Thanks in advance. Best Regards.
