Pie Charts

Pie charts are percentage-based. A pie chart models percentage-based data as individual slices of pie. Each data set must be defined as a new instance of the SingleValueColumn object. This tutorial shows how to configure your portlet to use pie charts.

Follow these steps:

1. Import the chart taglib along with the PieChartConfig and SingleValueColumn classes into your bundle’s init.jsp file:

   <%@ taglib prefix="chart" uri="http://liferay.com/tld/chart" %>
   <%@ page import="com.liferay.frontend.taglib.chart.model.percentage.pie.PieChartConfig" %>
   <%@ page import="com.liferay.frontend.taglib.chart.model.SingleValueColumn" %>
   

2. Add the following Java scriptlet to the top of your view.jsp:

   <%
   PieChartConfig _pieChartConfig = new PieChartConfig();
   
   _pieChartConfig.addColumn(
     new SingleValueColumn("data1", 85.4)
   );
   %>
   

3. Add the <chart> taglib to the view.jsp, passing the _pieChartConfig as the config attribute’s value:

   <chart:pie
     config="<%= _pieChartConfig %>"
   />
