Is it possible to toggle the visibility of plotBands? I would like to be able to turn specific plotBands off/on based on a checkbox event on the page.

Thanks

Hi,

Unfortunately, currently plot bands don't have "visible" option, but you can try using the following code:

Code:
    <script lang="javascript" type="text/javascript">
        $(document).ready(function () {

            var chartOptions = {
                title: { text: 'Plot Bands' },
                animation: { duration: 1 },
                axes: [
                    {
                        location: 'left',
                        type: 'linear',
                        majorGridLines: { strokeDashArray: [1, 3] },
                        plotBands: [
                            {
                                fillStyle: '#fcb441',
                                from: 40,
                                to: 60,
                                zIndex: 0, // Posible values - 0, 1, 2
                                title: 'Good'
                            },
                            {
                                fillStyle: '#e0400a',
                                from: 60,
                                to: 70,
                                zIndex: 0, // Posible values - 0, 1, 2
                                title: 'Very Good'
                            }
                        ]
                    }
                ],
                series: [
                    {
                        type: 'column',
                        data: [['A', 45], ['B', 35], ['C', 68], ['D', 50], ['E', 5], ['F', 44]]
                    }
                ]
            };

            $('#jqChart').jqChart(chartOptions);

            $('input[type=checkbox]').change(function () {
                var checked = this.checked;
                var value = this.id;

                var plotBands = [];


                if ($("#Checkbox1").prop('checked')) {
                    plotBands.push({
                        fillStyle: '#fcb441',
                        from: 40,
                        to: 60,
                        zIndex: 0, // Posible values - 0, 1, 2
                        title: 'Good'
                    });
                };

                if ($("#Checkbox2").prop('checked')) {
                    plotBands.push({
                        fillStyle: '#e0400a',
                        from: 60,
                        to: 70,
                        zIndex: 0, // Posible values - 0, 1, 2
                        title: 'Very Good'
                    });
                };


                chartOptions.axes[0].plotBands = plotBands;

                $('#jqChart').jqChart(chartOptions);

            });
        });
    </script>

</head>
<body>
    <div>
        <div id="jqChart" style="width: 500px; height: 300px;">
        </div>
    </div>
    <input id="Checkbox1" value="1" type="checkbox" checked="checked" /> Display "Good" <br />
    <input id="Checkbox2" value="2" type="checkbox" checked="checked" /> Display "Very Good"
</body>
