Bubble Charts
[This topic is pre-release documentation and is subject to change in future releases. Blank topics are included as placeholders.]
A bubble chart displays series as a set of symbols. Values are represented by the position of the point in the chart space and the size of the symbol. Categories are represented by different symbols in the chart. There is one type of bubble chart.
Bubble
A bubble chart displays each value series as data points in the chart space according to the X and Y values for the value series. A third value, Size, determines the size of the symbol for the data point. While category and series groups are optional, at least one of these groups is required to display meaningful data in the chart.

Values |
Required. The values in a value series determine the position of each data point in the chart. There are three values for each value series: X, Y, and Size. These three values are required. The value of X determines the position of the data point on the x-axis. The value of Y determines the position of the data point on the y-axis. The value of Size determines the size of the symbol for the data point. If the chart contains multiple value series, the chart displays multiple series in the chart and in the chart legend. A typical bubble chart contains non-aggregate expressions for values. The expression for X in the value chart area and the expression for the category group are also typically the same. |
Category groups |
Optional. Category values are displayed as data points within a series group. |
Series groups |
Optional. Series are displayed as groups of data points in the chart. Each series is displayed as separate series in the chart (each with a different color or symbol) and in the chart legend. |
Note
To display labels on the x-axis, the x-axis must be scalar. To make the x-axis scalar, in Chart Properties, click X Axis, and then select Numeric or time-scale values.
