Chart and Pie for data with hole.

Sample Image - chartnpie.jpg

Introduction

In my work, I always want to display several data series with hole together. Massimo Colurcio has developed a control to display data with hole, but it is not an easy way to use, especially when the data is very sparse, so I decide to develop my own control based on his work. And at the same time, I also want to show these data series in Pie.

How to use?

  1. Add the files in the source package to your project.
  2. Do initialization, see CChartView::OnInitialUpdate().
  3. Call Add of CDataChart to add datasets to the control.
    void Add( int nDatasetID, int nIndex, double nData );
  4. SetStyle(STYLE_LINE) for line chart.
  5. SetStyle(STYLE_PIE) for pie showing.

and that's all.
