Chart and Pie for data with hole

Introduction

In my work, I always want to display several data series with hole together. 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.
