Bubble charts are perfect for displaying three to five dimensions or measures of data. In addition to the traditional x- and y-axis, the size of the bubble represents a key measurement. You can show two more attributes by using the slice and/or slice by color features.
You will need at least one attribute and two measures in your Chart Builder search to successfully generate a bubble chart.
Bubble Size
The size of each bubble is determined by the measure you select under the Layout panel.
This chart type fully supports the slice and slice by color functionalities. You can also slice scatter charts.
