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

实际上两者都是条形图。我不知道为什么这个错误可以帮助我解决这个错误。它简短的代码; firstchart和createchart都说明了我指定系列类型的创建代码......... .................................................. .................................................. .....
答案 0 :(得分：1)
我自己找到了解决方案; 而不是
chart.Series[0].ChartType = System.Web.UI.DataVisualization.Charting.SeriesChartType.Bar;
chart.Series[1].ChartType = System.Web.UI.DataVisualization.Charting.SeriesChartType.Bar;
替换为
foreach (Series series in chart.Series)
{
series.ChartType = SeriesChartType.Bar;
}
