vb.net在每個布布的梯度風格的氣泡圖，使其看起來像一個球

Question

我有一個在下面的代碼在vb.net中的氣泡圖，我想使氣泡出現一個漸變stlyle看起來像球（而不是圓）

Dim xValues As Double() = {10.62, 75.54, 60.45} 
Dim yValues As Double() = {650.62, 50.54, 600.45} 
Dim size As Integer() = {10, 20, 30} 
Dim names As String() = {"a", "b", "c"} 


Chart5.Series("Series1").ChartType = SeriesChartType.Bubble 
Chart5.Series("Series1").Points.DataBindXY(xValues, yValues, size, names) 
Chart5.Series("Series1").MarkerStyle = MarkerStyle.Circle 
For i = 0 To 2 
     Chart5.Series("Series1").Points(i).Label = names(i) 
Next 

我想：

Chart_Analysis.Series("Series1").BackSecondaryColor = Drawing.Color.Green 
    Chart_Analysis.Series("Series1").MarkerColor = Drawing.Color.Blue 
    Chart_Analysis.Series("Series1").BackGradientStyle = GradientStyle.Center 

...和

For i = Region_From To Region_To 
     Chart_Analysis.Series("Series1").Points(i).Label = names(i) 
     Chart_Analysis.Series("Series1").Points(i).BackGradientStyle = GradientStyle.Center 
     Chart_Analysis.Series("Series1").Points(i).Color = Drawing.Color.Aqua 
     Chart_Analysis.Series("Series1").Points(i).BackSecondaryColor = Drawing.Color.Green 
    Next 

.. 。但沒有成功

關於如何實現這個3D /球效果的任何想法？

感謝

試着改變你的第一個選項

Chart_Analysis.Series("Series1").BackSecondaryColor = Drawing.Color.Green 
Chart_Analysis.Series("Series1").MarkerColor = Drawing.Color.Blue 
Chart_Analysis.ChartAreas("Series1").BackGradientStyle = GradientStyle.Center 

注意改變ChartAreas在第三行。我發現有時候你認爲你應該對這個系列進行編碼，但是你應該使用ChartAreas。
