3 /// This macro plays a recorded ROOT session showing how to perform various
4 /// interactive graphical editing operations. The initial graphics setup
5 /// was created using the following root commands:
6 /// ~~~{.cpp}
7 /// TRecorder *t = new TRecorder();
8 /// t->Start("graphedit_playback.root");
9 /// gStyle->SetPalette(1);
10 /// TCanvas *c2 = new TCanvas("c2","c2",0,0,700,500);
11 /// TH2F* h2 = new TH2F("h2","Random 2D Gaussian",40,-4,4,40,-4,4);
12 /// h2->SetDirectory(0);
13 /// TRandom r;
14 /// for (int i=0;i<50000;i++) h2->Fill(r.Gaus(),r.Gaus());
15 /// h2->Draw();
16 /// gPad->Update();
17 /// TCanvas *c1 = new TCanvas("c1","c1",0,0,700,500);
18 /// TH1F* h1 = new TH1F("h1","Random 1D Gaussian",100,-4,4);
19 /// h1->SetDirectory(0);
20 /// h1->FillRandom("gaus",10000);
21 /// h1->Draw();
22 /// gPad->Update();
23 ///
24 /// // Here the following "sketch" was done.
25 ///
26 /// t->Stop();
27 /// ~~~
28 /// Note: The previous commands should be copy/pasted into a ROOT session, not
29 /// executed as a macro.
30 ///
31 /// ### The interactive editing shows
32 /// - Object editing using object editors
33 /// - Direct editing on the graphics canvas
34 /// - Saving PS and bitmap files.
35 /// - Saving as a .C file: C++ code corresponding to the modifications is saved.
36 ///
37 /// ### The sketch of the recorded actions is
