Quick BI:Pie

Overview

• Scenarios

  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.
