PrimeFaces pieChart customization
<p>I am trying to add tooltip to legend of piechart and remove the description from it. Here is a basic demonstration of this(I added explanation to pictures) : 
<a href="https://i.stack.imgur.com/2efpy.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/2efpy.png" alt="enter image description here"></a>
In light of this image, I want to accomplish two things: </p>

<p>1-Firstly, I want to remove description from the legend section. As far as I understand, when I set the data source like this, it both sets tooltip of chart and legend label: </p>

<pre><code>pie.set(String category, Number data)
</code></pre>

<p>However, since I am getting description from database, it can be very long and this causes legend to overlap chart like this:
<a href="https://i.stack.imgur.com/qE1lq.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/qE1lq.png" alt="enter image description here"></a></p>

<p><strong><em>So, I only want to show data as tooltip on the chart and legend section(on the labels) and remove description from legend</em></strong>. Here is the javascript code(s) that I tried:</p>

<pre><code>function chartExtender() {

    this.cfg.legend = {
        show: true,
        highlighter: {
            show: true,
            useAxesFormatters: false
        },
        tooltipLocation: 'nw',
        placement: 'inside',
        rendererOptions: {//I tried that one and above highlighter respectively.
            highlighter: {
                tooltipFadeSpeed: 'slow',
                tooltipLocation: 'n',
                show: true
            }
        }
    };
    this.cfg.highlighter = {
        show: true,
        useAxesFormatters: false, // must be false for piechart   
        tooltipLocation: 'n',
        formatString: '%s = %d'
    };
}
</code></pre>

<p>2- Secondly, is there a way to completely customise data sources of legend and chart section? I dont want them bounded like this.</p>
