在使用Highcharts API的折线图中,在图例中还显示了系列以及线条和相同的名称。

我想要这样的https://jsfiddle.net/gh/get/library/pure/highcharts/highcharts/tree/master/samples/highcharts/legend/title/,但就我而言,系列名称要高于系列和图例。

Highcharts.chart('container', {
    title: {
        text: 'Monthly Average Temperature'
    },
    subtitle: {
        text: 'Source: WorldClimate.com'
    },
    xAxis: {
        categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun',
            'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
    },
    yAxis: {
        title: {
            text: 'Temperature (°C)'
        },
        plotLines: [{
            //value: 1,
            width: 1,
            color: '#808080'
        }]
    },
    tooltip: {
        valueSuffix: '°C'
    },
    legend: {
        title: {
            text: 'City<br/><span style="font-size: 9px; color: #666; font-weight: normal">(Click to hide)</span>',
            style: {
                fontStyle: 'italic'
            }
        },
        layout: 'vertical',
        align: 'right',
        verticalAlign: 'top',
        x: -10,
        y: 100
    },
    series: [{
        name: 'Tokyo',
        data: [7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2, 26.5, 23.3, 18.3, 13.9, 9.6]
    }, {
        name: 'New York',
        data: [-0.2, 0.8, 5.7, 11.3, 17.0, 22.0, 24.8, 24.1, 20.1, 14.1, 8.6, 2.5]
    }, {
        name: 'Berlin',
        data: [-0.9, 0.6, 3.5, 8.4, 13.5, 17.0, 18.6, 17.9, 14.3, 9.0, 3.9, 1.0]
    }, {
        name: 'London',
        data: [3.9, 4.2, 5.7, 8.5, 11.9, 15.2, 17.0, 16.6, 14.2, 10.3, 6.6, 4.8]
    }]
});

您可以将labelFormatter功能用于图例:

legend: {
    labelFormatter: function() {
        return ''
    },
    ...
}
