This image shows a sample bubble chart and a sample scatter chart. Both charts have four data series.

In the scatter chart, the series are represented by different shapes, viz. square, circle, diamond and plus sign.

In both charts, a tooltip displays information about a data item upon hovering. In the scatter chart, the Series, the Group, the X value and the Y value are shown. In the bubble chart, a Z value is also shown, where the Z value represents the bubble size.
