ComponentOne的C1Chart做饼状图怎么显示其百分比

为饼图添加百分比显示效果，实现代码： protected void Page_Load(object sender, EventArgs e) { if (IsPostBack) { return; } #region 设置饼图数据显示为百分比 PieSeries ps = (FpChart1.Model.PlotAreas[0] as FarPoint.Web.Chart.PiePlotArea).Series[0] as FarPoint.Web.Chart.PieSeries; double sumvalue = ps.Values.Sum(); for (int i = 0; i < ps.Values.Count; i++) { ps.Values[i] = (ps.Values[i] / sumvalue); } #endregion } 具体的实现方法，可以参照下面的博客/post/2012/11/14/%E4%B8%BA%E9%A5%BC%E5%9B%BE%E6%B7%BB%E5%8A%A0%E7%99%BE%E5%88%86%E6%AF%94%E6%98%BE%E7%A4%BA%E6%95%88%E6%9E%9C.aspx
