Bubble Chart - Bubble always circle

[Chris]

For the bubbles i has to define the horizontal and vertical size with the two values XValue2 and YValue2. Depending of the x- and y-axis and the values i get ellipses or so.

I would like generate always circles with only one value for the diameter and independent of the dimensions of the both axis.

How can i realize this in vb.net?

Regards and thanks
Chris

Hi Chris,

You can control the bubbles size by setting value to the BubbleSize property (e.g. chartSeries.Appearance.BubbleSize = 26)
Additionally you could determine the position of the circle by changing  XValue and YValue
Here is an example in VB:

 Dim chartSeries1 As New ChartSeries("My Series")
        chartSeries1.Type = ChartSeriesType.Bubble
        chartSeries1.Appearance.BubbleSize = 26
        RadChart1.Series.Add(chartSeries1)
        Dim item1 As New ChartSeriesItem(20)
        Dim item2 As New ChartSeriesItem(60)
        Dim item3 As New ChartSeriesItem(10)
        item1.XValue = 20
        chartSeries1.AddItem(item1)
        item2.XValue = 60
        chartSeries1.AddItem(item2)
        item3.XValue = 40
        chartSeries1.AddItem(item3)

        RadChart1.PlotArea.YAxis.AxisMode = ChartYAxisMode.Extended

Hope this helps.
