disable sorting in lineChart series in Primefaces?

Question

using Primefaces 5.0.4: consider the below plots:

series4.set(6.63,3000);
series4.set(6.72,2997.61);
series4.set(6.446636814,2877.63);

series4.set(2.127407915,1483.979464);
series4.set(2.30500294,1544.046998);

lineModel1.setStacked(true);
lineModel1.addSeries(series4); 

Axis xAxis=new CategoryAxis("Xdata");

lineModel1.getAxes().put(AxisType.X, xAxis);
Axis yAxis = lineModel1.getAxis(AxisType.Y);
yAxis.setLabel("YData");

Now I want the program to connect the dots in order which I gave, which is the order I added them to my series. But I do get them connected in sorted order. I think it is sorted by x-value. Is there a way to disable this auto sort. Please suggest.

In bean i set the extender to

lineModel1.setExtender("extend");

in xhtml:

<p:lineChart id="linear" value="#{catalogChartBean.lineModel1}" title="Linear Chart" />

in js:

function extend(){
   this.cfg=$.jqplot(this.cfg.id, this.cfg.data, {sortData:false});
   this.cfg.redraw(); 
      }

i don't think so this function is invoked even, because i wrote a simple window.alert and the extender dint invoke it.

Answer 1

I figured it out and made it work. I used <p:lineChart /> and it is not able to invoke the extender. Not sure WHY ? But i changed it to <p:chart/> and it worked.

Also to disable sorting i used this below js via extender.

<script language="javascript" type="text/javascript">
    function extnder() {
        this.cfg.sortData = false;
    }
</script>
