								<p>Use the <a href="wijmo_knockout_chart_annotation.wjflexchartannotationlayer.html">wjFlexChartAnnotationLayer</a> binding to add <a href="wijmo_chart_annotation.annotationlayer.html">AnnotationLayer</a> object to your
								KnockoutJS applications. For example:</p>
								<pre>&lt;p&gt;Here is a AnnotationLayer:&lt;/p&gt;
&lt;div data-bind="wjFinancialChart: { itemsSource: fData, bindingX: 'date', chartType:'Candlestick' }"&gt;
   &lt;div data-bind="wjFinancialChartSeries: { bindingX: 'date', binding: 'high,low,open,close' }"&gt;&lt;/div&gt;
   &lt;div data-bind="wjFlexChartAnnotationLayer: {}"&gt;
       &lt;div data-bind="wjFlexChartAnnotation: { type: 'Rectangle', content: 'E',height:20, width:20,attachment:'DataIndex',pointIndex: 10}"&gt;&lt;/div&gt;
       &lt;div data-bind="wjFlexChartAnnotation: { type: 'Ellipse', content: 'E',height:20, width:20,attachment:'DataIndex',pointIndex: 30}"&gt;&lt;/div&gt;
   &lt;/div&gt;
