In this example, the bubble chart displays GDP values for the G20. A point's size indicates the country population and the color indicates the HPI.
In this example, each data source item that is used to create a bubble contains four values:
- Country - Stores data for bubble arguments shown on the x-axis.
- Gdp - Stores data for bubble values shown on the y-axis.
- Population - Stores data for bubble weight values that define the bubble size.
- Hpi - Stores values that a colorizer uses to determine the bubble color.
To paint bubbles according to the ranges of underlying values, assign a CustomValueBandPointColorizer to a BubbleSeries' PointColorizer property.
The colorizer's ValueProvider returns HPI values that are used to determine point colors.
