Bubble Charts

The Bubble chart is an extension of the Point chart but each point can be a circle or oval of any size or dimension. Instead of using just the XValue and YValue, the Bubble chart uses XValue/XValue2, and YValue/YValue2 pairs to define the dimensions of each bubble. Bubble charts are commonly used to display financial information where the size of the bubble can be proportionate to the data values.

To change the size of all bubbles in a series, but to not distort the dimensions of the bubble, assign the Series.Appearance.BubbleSize property.

To create a vertical Bubble Chart set the SeriesOrientation property to Vertical. Set the RadChart DefaultType property or ChartSeries.TypeBubble. Add one or more chart series to the Series collection.  Add one or more chart items to the series Items collection. Populate numeric values for XValue, XValue2, YValue and YValue2 properties of each chart series item.

To create a horizontal Bubble Chart set the SeriesOrientation property to Horizontal. Set the RadChart DefaultType property or ChartSeries.TypeBubble. Add one or more chart series to the Series collection.  Add one or more chart items to the series Items collection. Populate numeric values for XValue, XValue2, YValue and YValue2 properties of each chart series item.
