   Rebinning Tab:                                                     
      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 for example:                           
         TFile f("hsimple.root");                                     
         hpxpy->Draw("Lego2");              // non ntuple histogram   
         ntuple->Draw("px:py","","Lego2");  // ntuple histogram       
    Non ntuple histogram:                                             
       'Rebin': with the Sliders (one for the x, one for the y axis)  
                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 sliders 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 be 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.
