得到錯誤

Chart Area Axes - The chart area contains incompatible chart types. For example, bar charts and column charts cannot exist in the same chart area. 

爲

 Chart Chart1 = FirstChart(dt1);

其實兩者都是酒吧chart.I不爲什麼這個錯誤誰能幫助我解決這個錯誤。它簡短的代碼; firstchart和createchart exicutes創建代碼，我指定了系列類型............................... .................................................. .................................

我自己找到解決方案;的 代替

chart.Series[0].ChartType = System.Web.UI.DataVisualization.Charting.SeriesChartType.Bar; 
chart.Series[1].ChartType = System.Web.UI.DataVisualization.Charting.SeriesChartType.Bar; 

替換

foreach (Series series in chart.Series) 
{ 
     series.ChartType = SeriesChartType.Bar; 
}
