title: vb.net bubble chart with gradient style in each buble to make it look like a ball
body: <p>I have a bubble chart in vb.net with the code below and I would like to make the bubbles appear with a gradient stlyle to look like a ball (rather than a circle)</p>
  
  <pre><code>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
  </code></pre>
  
  <p>I tried:</p>
  
  <pre><code>    Chart_Analysis.Series("Series1").BackSecondaryColor = Drawing.Color.Green
      Chart_Analysis.Series("Series1").MarkerColor = Drawing.Color.Blue
      Chart_Analysis.Series("Series1").BackGradientStyle = GradientStyle.Center
  </code></pre>
  
  <p>... and </p>
  
  <pre><code>    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
  </code></pre>
  
  <p>... but with no success</p>
  
  <p>Any ideas on how to achive this 3d/ball effect?</p>
  
  <p>Thanks</p>
