Bubble Chart
A bubble chart draws bubbles for each point in a series. The chart expects three values per bubble: the domain (commonly the X-axis) value, the range (commonly the y-axis) value, and a third value (the Z value) that determines the size of the bubble to draw around the point.
The size of the bubble is derived from an algorithm that takes the Z value, divides it by the maximum Z value in the dataset, then multiplies that number by the max-bubble-size property value. See the section on required properties below for more information on the max-bubble-size property.
Dataset Guidelines
This chart expects its data as an XYZ dataset.
Required Properties
The following properties are required:
chart-type
<chart-type>BubbleChart</chart-type>
dataset-type
<dataset-type>XYZSeriesCollection</dataset-type>
max-bubble-size
The max-bubble-size property is defaulted to zero, so in order to see your bubbles, you'll need to set this property! The value should be between 1 and 100, as a percentage of smaller to larger.
<max-bubble-size>90</max-bubble-size>
The example below contains the full set of additional supported properties with comments on its purpose and valid values. It is recommended that new users start with this example as a starting place for building your first flash chart.
Example
The following chart definition will produce the chart in the example below.
