## Class Description

      TH1Editor
      Editor for changing TH1 histogram attributes, rebinning & fitting.
      For all possible draw options (there are a few which are not imple-
      mentable in graphical user interface) see THistPainter::Paint in
      root/histpainter/THistPainter.cxx

/* */

/* */

      These changes can be made via the TH1Editor:
        Style Tab:
          'Line'     : change Line attributes (color, thickness)
                       see TAttLineEditor
          'Fill'     : change Fill attributes (color, pattern)
                       see TAttFillEditor
    	'Title'    : TextEntry: set the title of the histogram
          'Histogram': change the draw options of the histogram
              'Plot' : Radiobutton: draw a 2D or 3D plot of the histogram
                       according to the Plot dimension there will be
                       different drawing possibilities (ComboBoxes/
                       CheckBoxes)
        2d Plot:
          'Error'   : ComboBox: add different error bars to the histogram
                      (no errors, simple, ...,  see THistPainter::Paint
          'Add'     : ComboBox: further things which can be added to the
                      histogram (None, simple/smooth line, fill area
          'Simple Drawing': CheckBox: draw a simple histogram without
                      errors (= "HIST" drawoption). In combination with
                      some other draw options an outer line is drawn on
                      top of the histogram
          'Show markers': CheckBox: draw a marker on to of each bin (="P"
                      drawoption)
          'Draw bar chart': CheckBox: draw a bar chart (="B" drawoption)
                      change the Fill Color with Fill in the Style Tab
                      => will show Bar menue in the Style Tab
          'Bar option': CheckBox: draw a bar chart (="BAR" drawoption)
                      => will show Bar menue in the Style Tab
        3d Plot:
          'Type'    : ComboBox: set histogram type Lego-Plot or Surface
                      draw(Lego, Lego1.2, Surf, Surf1..5)
                      see THistPainter::Paint
          'Coords'  : ComboBox: set the coordinate system (Cartesian, ..
                      Spheric) see THistPainter::Paint
          'Error'   : see 2D plot
          'Bar'     : change the bar attributes
                'W' : change Bar Width
                'O' : change Bar Offset
          'Percentage': specifies the percentage of the bar which is drawn
                        brighter and darker (10% == BAR1 drawoption)
          'Horizontal Bar': draw a horizontal bar chart

          'Marker'   : change the Marker attributes (color, appearance,
                       thickness) see TAttMarkerEditor

/* */

          This Tab has two different layouts. One is for a histogram which
          is not drawn from an ntuple. The other one is available for a
          histogram which is drawn from an ntuple. In this case the rebin
          algorithm can create a rebinned histogram from the original data
          i.e. the ntuple.
          To see te differences do:
             TFile f("hsimhe differences do:
             TFile f("hsimple.root");
             hpx->Draw("BAR1);         // non ntuple histogram
             ntuple->Draw("px");       // ntuple histogram
        Non ntuple histogram:
           'Rebin': with the Slider the number of bins (shown in the field
                    below the Slider) can be changed to any number which
                    divides the number of bins of the original histogram.
                    Pushing 'Apply' will delete the origin histogram and
                    replace it by the rebinned one on the screen
                    Pushing 'Ignore' the origin histogram will be restored
        Histogram drawn from an ntuple:
           'Rebin'  with the slider the number of bins can be enlarged by
                    a factor of 2,3,4,5 (moving to the right) or reduced
                    by a factor of 1/2, 1/3, 1/4, 1/5
           'BinOffset': with the BinOffset slider the origin of the
                    histogram can be changed within one binwidth
                    Using this slider the effect of binning the data into
                    bins can be made visible => statistical fluctuations
           'Axis Range': with the DoubleSlider it is possible to zoom into
                    the specified axis range. It is also possible to set
                    the upper and lower limit in fields below the slider
           'Delayed drawing': all the Binning sliders can set to delay
                    draw mode. Then the changes on the histogram are only
                    updated, when the Slider is released. This should be
                    activated if the redrawing of the histogram is too
                    time consuming.
