              Create an enhanced version of the histogram 
                demonstration by adding additional textfields to allow the 
                user to vary the number of bins and the input range.
 
Use a JList 
                or JRadioButton 
                widget to select whether to draw vertical bars, symbols, or error 
                bars for the bin values. 
 
Enhance the HistogramStat 
                class with more calculations of the moments less prone to round-off 
                erros. (See, for example, Press 
                or Bisset)
 
Modify the histogram statistics 
                display such as that instead of a popup frame, display the values 
                within the applet browser window.   |
