Scatter Charts

Scatter charts contain multiple sets of data. A scatter chart models the data as individual points. Each data series (created with the addColumns() method) is defined with a new instance of the MultiValueColumn object, which takes an ID and a set of values. Follow these steps to configure your portlet to use scatter charts.

Import the chart taglib along with the ScatterChartConfig and MultiValueColumn 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.point.scatter.ScatterChartConfig" %>
<%@ page import="com.liferay.frontend.taglib.chart.model.MultiValueColumn" %>

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

<%
ScatterChartConfig _scatterChartConfig = new ScatterChartConfig();

_scatterChartConfig.addColumns(
  new MultiValueColumn("data1", 100, 20, 30),
  new MultiValueColumn("data2", 20, 70, 100));
%>

Add the <chart> taglib to the view.jsp, passing the _scatterChartConfig as the config attribute’s value:
```
<chart:scatter
  config="<%= _scatterChartConfig %>"
/>
```
