在同一個圖表上繪製兩個不同的圖形

Question

我正在使用MSChart控件來繪製一些數據，但我想在同一個圖表上繪製兩個不同的圖形 。例如，使用條形圖（系列1）和餅圖（系列2）

我試圖通過使用以下代碼使用單個圖表來顯示兩個不同的圖表 它顯示數據正確，但是一個問題是我想要以顯示兩個圖（餅圖，柱狀圖），但它顯示

能否評價一下這個

注意任何一個幫助（「兩個餅圖」）：我用一個圖表所有這些操作

    var results = kpiChartControl.HitTest(pos.X, pos.Y, false, ChartElementType.DataPoint); 
    foreach (var result in results) 
    { 
     if (result.ChartElementType == ChartElementType.DataPoint)

只是猜...贏了這段代碼是否強制所有圖表成爲餅圖？

foreach (Series chartSeries in kpiChartControl.Series) 
    { 
     chartSeries.ChartType = SeriesChartType.Pie; 

     chartSeries["PieLabelStyle"] = "Outside"; 
     chartSeries["DoughnutRadius"] = "30"; 
     chartSeries["PieDrawingStyle"] = "SoftEdge"; 

     chartSeries.BackGradientStyle = GradientStyle.DiagonalLeft; 
    }

如果這樣沒有幫助，然後嘗試打破你的代碼分解成更小的方法，然後評論每一位出反過來 - 那麼你就可以瞭解每一位做什麼。
