In this article the original Pie Chart creation code moved closer to a real world scenario, one where the user inputs the data at run time.

     The Invalidate method was introduced and we saw how this forces a repaint of the control on which it is called.   

   A  HatchBrush was used to fill the pie segments with patterns selected from the HatchStyle enumeration.

 In summary, this article included coverage of the following :


  •  ArrayList
  •  Brush
  •  ColorDialog
  •  Dispose
  •  DrawPie
  •  DrawRectangle
  •  DrawString
  •  FillPie
  •  FillRectangle
  •  Font object
  •  HatchBrush
  •  HatchStyle
  •  Invalidate
  •  Pen
  •  StartAngle
  •  Structure
  •  SweepAngle
  •  System.Enum.GetNames
  •  System.Enum.Parse

If you have read all three articles in this series so far, I hope you will now be feeling very comfortable with several of the key basic Graphics Class methods, properties and techniques.   And I also hope that you will be looking forward to charting some new territory in Part 4 where we return to create a better bar chart.
