Question

I have a plot that is similar to the one shown in this JS Fiddle:

$(function () {
    $('#container').highcharts({
        legend: {
            align: "left"
        },
        chart: {
            type: 'spline'
        },
        title: {
            text: 'Snow depth at Vikjafjellet, Norway'
        },
        subtitle: {
            text: 'Irregular time data in Highcharts JS'
        },
        xAxis: {
            type: 'datetime',
            dateTimeLabelFormats: { // don't display the dummy year
                month: '%e. %b',
                year: '%b'
            },
            title: {
                text: 'Date'
            }
        },
        yAxis: {
            title: {
                text: 'Snow depth (m)'
            },
            min: 0
        },
        tooltip: {
            headerFormat: '<b>{series.name}</b><br>',
            pointFormat: '{point.x:%e. %b}: {point.y:.2f} m'
        },

        plotOptions: {
            spline: {
                marker: {
                    enabled: true
                }
            }
        },

        series: [{
            name: "Winter 2012-2013",
            // Define the data points. All series have a dummy year
            // of 1970/71 in order to be compared on the same x axis. Note
            // that in JavaScript, months start at 0 for January, 1 for February etc.
            data: [
                [Date.UTC(1970, 9, 21), 0],

            ]
        }, {
            name: "Winter 2014-2015",
            data: [
                [Date.UTC(1970, 10, 25), 0],

                [Date.UTC(1971, 4, 10), 2.56],
                [Date.UTC(1971, 4, 15), 2.39],
                [Date.UTC(1971, 4, 20), 2.3],
                [Date.UTC(1971, 5, 5), 2],
                [Date.UTC(1971, 5, 10), 1.85],
                [Date.UTC(1971, 5, 15), 1.49],
                [Date.UTC(1971, 5, 23), 1.08]
            ]
        }]
    });
});

What I would like to do is allow a user to click on one of these series, which would hide the other series on the plot. How do I do that?

Example: Clicking on the black series would hide the green and blue series.

你可以尝试实现类似这样的东西

         series:{
                events: {
                        legendItemClick: function (e) {


                            var seriesArr=$('#container').highcharts().series;
                            var visible = this.visible;
                            var index = this.index;
                            for(var i=0; i<seriesArr.length;i++)
                            {
                                if(i!=index)
                                {
                                    seriesArr[i].setVisible(false, false);
                                }
                            }

                            this.visible=false;  


                        }
                    }
        }

您需要做的是隐藏所有系列中的点击并显示显示单击的系列。我在下面列出了您需要的代码，这里是fiddle。这样您就可以显示用户点击的图表。此外，你可以有一个＆＃39;显示全部＆＃39;按钮，重绘整个图表。希望这会有所帮助。

plotOptions: {
            spline: {
                marker: {
                    enabled: true
                }
            },
             series: {
                cursor: 'pointer',
                events: {
                    click: function (event) {
                      var chart = $('#container').highcharts();

                      $(chart.series).each(function(){
                          this.setVisible(false, false);
                      });
                      this.show();
                    }
                }
            }
        },
