折线图中的鼠标悬停或单击事件 [英] Mouse Hover or Click Event in Line Chart

问题描述

当用户将鼠标悬停在#chart上时，将绘制第二个数据.

When user hovers the mouse on the #chart, then second data is drawn.

但是我想知道用户何时将鼠标悬停在第一条数据线上而不是#chart上，然后绘制第二条数据线.

However I would like to know when user hovers the mouse on the first data line by itself not #chart then second data line is drawn.

function createChart() {
    $("#chart")
        .kendoChart({
            xAxis: {},
            yAxis: {},
            seriesDefaults: {type: "scatterLine" },
            series: [{data: stats2},{name:"gmail"}],
  })
}

var isHover = false;
$("#chart").hover(
    function () {
    if (!isHover) {
        var chart = $("#chart").data().kendoChart;
        chart.options.series[0].data = stats2;
        chart.options.series[0].name="yahoo";
        chart.redraw();
        isHover = true;
    }
}, function () {
    if (isHover) {
        var chart = $("#chart").data().kendoChart;
        chart.options.series[0].data = stats;
        chart.options.series[0].name="";
        chart.redraw();
        isHover = false;
    }
});

推荐答案

在createChart中添加此内容(并将函数替换为所需的行为).此示例仅向控制台写入"hello".

Add this within createChart (and replace the function with your desired behavior). This example just writes "hello" to the console.

function createChart() {
    $("#chart")
        .kendoChart({
            xAxis: {},
            yAxis: {},
            seriesDefaults: {type: "scatterLine" },
            series: [{data: stats2},{name:"gmail"}],
            seriesHover: function(e) {
                console.log("hello");
            }
        })
}
