PrimeFaces - customise Date Chart

Question

I am using PrimeFaces 3.4.1 to plot time chart (Date on x-axis, int value on y-axis).

At the moment I have something like that:

In Java, fill your LineChartSeries objects with times in milliseconds using Date#getTime().

On the facelets side, download from jqPlot site and import the following jqPlot plugins:

<h:outputScript name="Javascript/jqplot.canvasAxisTickRenderer.js" />
<h:outputScript name="Javascript/jqplot.canvasAxisTickRenderer.min.js" />
<h:outputScript name="Javascript/jqplot.dateAxisRenderer.js" />
<h:outputScript name="Javascript/jqplot.dateAxisRenderer.min.js" />

And use this js extender for p:lineChart component:

function chartExtender() {
    this.cfg.axes = {
        xaxis : {
            renderer : $.jqplot.DateAxisRenderer, 
            rendererOptions : {
                tickRenderer:$.jqplot.CanvasAxisTickRenderer
            },
            tickOptions : { 
                fontSize:'10pt',
                fontFamily:'Tahoma', 
                angle:-40
            }
        },
        yaxis : {
            rendererOptions : {
                tickRenderer:$.jqplot.CanvasAxisTickRenderer
            },
            tickOptions: {
                fontSize:'10pt', 
                fontFamily:'Tahoma', 
                angle:30
            }
        }               
    };
    this.cfg.axes.xaxis.ticks = this.cfg.categories;
}
