How to add data and configure styles for a pie chart (dashboard)-Quick BI(Quick BI)-阿里云帮助中心

A pie chart is used to analyze the proportion of data. For example, you can use a pie chart to obtain the proportion of each portion of a category. This topic describes how to add data to a pie chart and configure the style of a pie chart.

Prerequisites

A dashboard is created. For more information, see Create a dashboard.

Overview

Scenario
In most cases, a pie chart is used to display the distribution of dimension values based on the proportion of metrics. Data can be expressed by using various methods such as data highlights and data magnification.
Benefits
- Easy-to-use interactive operations: A pie chart allows you to switch between metrics and configure filters.
- Abundant data visualization: The chart type of a pie chart can be a pie and a ring. A pie chart allows you to configure parameters, such as Show Labels.
- Various interactive options: You can add remarks or endnotes to metrics in pie charts. You can also add links to pie charts to interact with external systems.
Example

Limits

Take note of the following limits when you add data to a pie chart:

You can add 1 to 10 measures to the Central Angle (Mea.) field.
You can add only one dimension to the Labels (Dim.) field.

Configure a pie chart

On the Field tab, select the required dimension and measure fields.
- In the Dimension list, find area, and then double-click or drag it to the Labels (Dim.) field.
- In the measure list, find shipping_cost, price, and order_amt, and then double-click or drag them to the Central Angle (Mea.) field.
Click Update.
The updated chart appears as shown in the following figure.
Configure the Auto Refresh parameter.
When enabled, the chart data refreshes automatically. For example, if you set the refresh interval to 5 minutes, the chart data updates every 5 minutes.

Configure the style of a pie chart

On the Field tab of the chart designer, you can configure formats for multiple fields at once.
