    Hello Support,

    Pie section shows value of the section, when show labels is true and percentage if it is specified in formatSettings.

    On mouseover or tooltip I can see John:8000.

    I want to show it all together and also the name of the series in the label besides the pie section.

    presently it shows just 8000, I want to show it like John: 8000(20%)

    How can I acheive this?

    // setup the chart
    $('#jqxChart').jqxChart(settings);
    });
    </script>
    </head>
    <body class='default'>
    <div id='host' style="margin: 0 auto; width: 699px; height: 400px;">

    top: 0px;">
    </div>
    </div>
    </body>
    </html>

    and here is the contents of the file sample.txt:

    John, 8000
