    In a stacked chart out of three legends for example if none of the bar has value greater than 0 then i need to hide the legend as well.
    How to Implement?

    Hello arunthatham,

    Here is how to hide a particular series’ legend:

    $('#chartContainer .jqx-chart-legend-text').eq(0).parent().hide();

    where chartContainer is the id of the jqxChart and 0 is the series index.

    Hello arunthatham,

    You can use the recursive function addhandler demonstrated in the following example as a workaround:
