Bubble Chart

A Bubble chart is a variation of the Scatter Plot. Aggregated data is grouped by dimension into circles displayed on an x/y axis. Additional measures change the size or color of the circles. A Bubble chart can represent up to four measures for your chosen dimensions (x, y, size, and color).
Features Quantity Notes
Required Dimensions 1+ Minimum 1, no limit, null dimensions optional.
Required Measures 2-4 Measure 1 = x axis, Measure 2 = y axis, Measure 3 = bubble size, Measure 4 = bubble color.

Use a Bubble chart to show a correlation between the x measure and the y measure. When you do not expect a correlation, you can use a Bubble chart to understand the distribution and influence of multiple factors.
Bubble Chart Examples

Create a new Bubble chart. Choose a Data Source. This example graphs employment statistics for all 50 United States for the years 1980-2015. The data is available at the University of Kentucky website.

State_name is a handy dimension for this data. Use the average Unemployment_rate as the X Axis, and the average Unemployment total for the Y Axis. Increase the # of Groups to 50 to create an individual bubble for each state.
