Question

在极坐标图中，仅将鼠标悬停在点上时显示工具提示，而不像this image 感谢TorsteinHønsi的这张图表

    <script src="http://code.highcharts.com/highcharts.js"></script>
    <div id="container" style="height: 400px"></div>
    <script>
    $(function () {
        $('#container').highcharts({
            chart: {

                type: 'scatter'
            },
            plotOptions: {
        series: {
            stickyTracking: false
        }
    },
    tooltip: {
        snap: 0
    },

            series: [{
                lineWidth:2,
                data: [29.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4]        
            }]
        });
    });
    </script>

将stickyTracking属性设置为false：

Highcharts.chart('container', {
    chart: {
        polar: true
    },
    series: [{
        stickyTracking: false,
        data: [43934, 52503, 57177, 69658, 97031, 119931, 137133, 154175]
    }]
});
