Set bubble size (Z-axis)

A bubble chart is similar to a scatter chart, but data points are represented as bubbles. It also introduces a third dimension, typically shown by the size of the bubbles. This means each data point includes three values: X, Y, and Z.

1. In the chart panel, click Data Series to open the dropdown menu.

2. In the Series tab, click the series to expand it.

3. From the dropdown next to Z, select the column you want to use as the Z-axis.

A quicker way to select a series is to click it directly on the chart.
