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?
- Add the files in the source package to your project.
- Do initialization, see
CDataChart to add datasets to the control.
void Add( int nDatasetID, int nIndex, double nData );
SetStyle(STYLE_LINE) for line chart.
SetStyle(STYLE_PIE) for pie showing.
and that's all.
