    <p>I am trying to use the extender atttribute on a line chart in PrimeFaces 3.4. I need to use extender to format the x-axis with date/time values. Doing this without extender is not an option as there are too many data points and the labels simply overwrite if I use the default PF lineChart attributes. When I setup the the code as shown below, I get an x-axis with no values displayed; all I can see is the x-axis. See pic for more details. How can I set this up so that the x-axis displays time in hh:mm format ?</p> <p><img src="https://i.stack.imgur.com/XRzrx.png" alt="Chart Displayed"></p> <p>XHTML Code</p> <pre><code>&lt;script type="text/javascript" src="#{request.contextPath}/js/plugins/jqplot.dateAxisRenderer.min.js"&gt;&lt;/script&gt; &lt;script type="text/javascript" src="#{request.contextPath}/js/plugins/jqplot.canvasAxisTickRenderer.min.js"&gt;&lt;/script&gt; &lt;script type="text/javascript"&gt; function loginRateChartExt() { this.cfg.axes = { yaxis: { numberTicks: 10, label: 'Logins per minute -&gt;', labelRenderer: $.jqplot.CanvasAxisLabelRenderer, labelOptions: { fontFamily: 'Verdana', fontSize: '8pt' }, }, xaxis: { renderer: $.jqplot.DateAxisRenderer, rendererOptions: { tickRenderer:$.jqplot.CanvasAxisTickRenderer }, tickOptions: { formatString:'%H:%M' }, label: 'Time of day -&gt;', labelRenderer: $.jqplot.CanvasAxisLabelRenderer, labelOptions: { fontFamily: 'Verdana', fontSize: '8pt' } } }; } &lt;/script&gt; &lt;p:lineChart id="loginRateChart" value="#{loginRateBean.chartModel}" extender="loginRateChartExt" /&gt; </code></pre> <p>Bean Code</p> <pre><code>for(int i = 0; i &lt; workerBean.getSize(); i++) { // worker bean has the data for (String key : workerBean.getValueKeys()) { // each key refers to a series // chartSeriesMap is a map that contains all the series // workerBean.getKeyAt(i) returns Date // workerBean.getValueAt(i, key) returns a Number chartSeriesMap.get(key).set(workerBean.getKeyAt(i), workerBean.getValueAt(i, key).floatValue()); } } for (String string : workerBean.getValueKeys()) { chartModel.addSeries(chartSeriesMap.get(string)); } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
