Last change on this file since 12880 was 12880, checked in by tbretz, 10 years ago
Removed some old workarounds hopefully not necessary anymor with newer root version -- tested with 5.32.00 so far.

27// MHSectorVsTime
28//
29// Display the mean and its variance vs time of the whole camera or a
30// single sector
31//
32// 1) If no other title is given the rule for the y-axis is used.
33// 2) If the MH3 has a non-default title (MH3::SetTitle called)
34// this title is set as the histogram title. It can be used to overwrite
35// the axis titles. For more information see TH1::SetTitle, eg.
36// SetTitle("MyGraph;;Counts");
37// The title for the x-axis is ignored and set automatically (MAKE SURE
38// YOU HAVE TWO SEMICOLON!)
39//
40// Example:
41// --------
42// // Initialize histogram
43// MHSectorVsTime hist1;
44// hist1.SetNameTime("MTimeCurrents");
45// hist1.SetTitle("Title for your Graph;;Q [phe]");
46//
47// // Define sectors you want to display the mean from
48// TArrayI s0(3);
49// s0[0] = 6;
50// s0[1] = 1;
51// s0[2] = 2;
52//
53// // Define area index [0=inner, 1=outer]
54// TArrayI inner(1);
55// inner[0] = 0;
56//
57// // Don't call this if you want to have all sectors
58// hist1.SetSectors(s0);
59//
60// // Don't call this if you want to have all area indices
61// hist1.SetAreaIndex(inner);
62//
63// // Task to fill the histogram
64// MFillH fill1(&hist1, "MCameraDC");
65//
66//
67// Class Version 2:
68// ----------------
69// + Double_t fMinimum; // User defined minimum
70// + Double_t fMaximum; // User defined maximum
