以下的例子介绍了g:textAnnotation标签使用方法，在创建jsp页面之前，需要创建为数据表提供数据的托管Bean：

@ManagedBean(scope=ManagedBeanScope.REQUEST)
public class JDKData extends ArrayDataModel
{
    public static class JDKDataItem {
        private String releaseVersion;
        private int classCount;

     public JDKDataItem(String releaseVersion, int classCount) {
         this.releaseVersion = releaseVersion;
         this.classCount = classCount;
     }
    
   ......

    private static final JDKDataItem[] data = new JDKDataItem[] {
        new JDKDataItem("JDK 1.0", 212),
        new JDKDataItem("JDK 1.1", 504),
        new JDKDataItem("JDK 1.2", 1520),
        new JDKDataItem("JDK 1.3", 1842),
        new JDKDataItem("JDK 1.4", 2991)
    };

    ......
}

下面是使用g:textAnnotation标签的代码：

<g:lineChart title="Java Standard Class Library" xAxisLabel="Release" yAxisLabel="Class Count" drawMarkers="true" showLegend="false"> 
  <g:title value="Number of Classes By Release" /> 
  <g:title value="Source: Java In a Nutshell (4th Edition) by David Flanagan (O'Reilly)" font="SansSerif,normal,10" position="BottomRight" /> 
  <g:dataSeries value="#{JDKData}" var="x" rows="10"> 
    <g:dataLabel value="#{x.releaseVersion}" /> 
    <g:dataItem legend="Classes" value="#{x.classCount}" /> 
  </g:dataSeries> 
  <g:textAnnotation xValue="JDK 1.0" yValue="212" text="Released 18-May-1995" anchor="Bottom" drawArrow="true" arrowAngle="-90" rotationAngle="-60"/> 
  <g:textAnnotation xValue="JDK 1.1" yValue="504" text="Released 12-Sep-1997" anchor="Left" drawArrow="true" arrowAngle="0" arrowLength="50" /> 
  ...... 
</g:lineChart>
