This topic describes the overview, examples, and deletion of a polar diagram.
A polar diagram compares multiple data values. It is used for comparing enumerated data, such as data based on multiple regions.
Similar to a pie chart, a polar diagram consists of slices. Labels of slices are determined by the dimension, such as the area and product type. Arc radiuses are determined by the measure, such as order numbers and order amounts.
You can select a maximum of one dimension for labels. The minimum number of dimension values is three. The maximum number of dimension values is 12. You can select a maximum of one measure for arc radiuses.
The following example uses the company_sales_record dataset.
- Log on to the Quick BI console.
- Click Datasets to go to the Datasets page.
- Select the company_sales_record dataset and click Create Dashboard.
Note If you use Quick BI Enterprise Standard, you need to select Standard or Full Screen as the dashboard display mode. The following example uses Standard.
- Click the Polar Diagram icon and an empty chart appears on the dashboard.
- On the Data tab page, select a dimension and a measure.
In the Dimensions list, locate the area field and add it to the Label (Dimensions) section. In the Measures list, locate the order_number field and add it to the Arc Radius (Measures) section, as shown in the following figure.Note Make sure that you have converted the dimension type from String to Geo for the area dimension. For more information, see Change the dimension type.
- Click Update and the chart is updated.
- On the Style tab page, you can configure the title, layout, legend, measures, and series settings.
- Click Save to save the dashboard.
Configure the style
- In the Basic Information section, you can configure the title name, title color, description,
hyperlink, and background color. This example uses Dark as the background color.
Note For jumping to a report or an external page, select Show Hyperlink and enter a name and an address.
- In the Layout section, you can configure the legend position, whether to show tooltips, label style, leaders, and radiuses. The example uses Name, Value (Percentage) as the label style and uses Right as the legend position.
- In the Measures section, you can configure the data format and the number of decimal places. This example uses 2 as the number of decimal places.
- In the Series Setting section, you can configure aliases for the dimensions and slice colors.
Click Update and the chart is shown as follows.
