This topic introduces bubble charts, including an overview and an application example. This topic also describes how to configure the style of a bubble chart and how to delete a bubble chart.
A bubble chart is similar to a scatter chart. The only difference is that the bubble chart allows you to specify a measure to indicate the bubble size.
A bubble chart consists of an x-axis, a y-axis, a category, bubble colors, and bubble sizes. The x-axis is determined by a dimension or measure. The y-axis is determined by a measure. The category is determined by a dimension. Bubble colors are determined by a dimension or measure. Bubble sizes are determined by a measure.
- You can specify only one dimension or measure for the x-axis and only one measure for the y-axis.
- You can specify the same dimension or measure for bubble colors as that for the x-axis, y-axis, or category.
- You can specify the same measure for sizes as that for the x-axis or y-axis.
Scenario: Compare the unit prices and order quantities of different products in different regions. The following example uses the company_sales_record dataset to describe the application of a bubble chart.
- In the left-side navigation pane of the Workspace page, click Datasets.
On the Datasets page that appears, find the company_sales_record dataset, and click the icon in the Actions column.Note If you are using Quick BI Enterprise Standard, select Standard or Full Screen as the dashboard type. In this example, Standard is selected.
- Click the icon. A bubble chart appears in the display area of the dashboard.
- Click the Data tab, select the required dimensions and measures, and add them to the relevant fields.
- Click Update. The chart is updated.
- Click the Style tab and configure parameters in the Basic Information, Chart Style, Axes, Functionality, and Series Settings sections.
- Click the Advanced tab and configure parameters in the Advanced Settings and Metric Analysis sections. You can configure the trendline and cluster analysis only if a measure
is specified for the x-axis. For more information, see Drilling, filter interaction, and hyperlinkand Metric analysis.
Note After Clustering is selected on the Advanced tab, the value of the Color (Dim. or Mea.) field becomes Clustering, and similar measure values are displayed as a cluster.
- Click Save in the upper-right corner. In the Save Dashboard dialog box that appears, enter a name for the dashboard and click OK.
Configure parameters on the Style tab
- In the Basic Information section, configure Show Title and Description, Show Link, and Custom Background.
Note If you want the user to be redirected to a report or an external page, select Show Link and specify Link Text and Link Address.
- In the Chart Type section, specify Show Labels, Show Legend, Data Point Color, and Bubble Size.
Note The Data Point Color field is available only when the Color (Dim. or Mea.) field is specified. If the Color (Dim. or Mea.) field is set to a dimension, you can select a hue for the dimension or specify a color for each value of the dimension. If the Color (Dim. or Mea.) field is set to a measure, you must specify the value range and the number of intervals, and then specify a color for each interval.
- In the Axes section, configure the basic information about the x-axis and the y-axis.
- In the Functionality section, enable the four-quadrant feature.
Note This feature can be enabled only when measures are specified for the x and y axes.
- In the Series Settings section, specify Display Name and Number Formatting for each measure. If Number Formatting is set to Customer, specify the data format (Number of Percentage) and set Decimal.
Delete a chart
Perform the following steps to delete a chart:
- Click the icon in the upper-right corner of a chart.
