官网有一个例子关于Highcharts 多图联动,链接地址,但是例子不是在vue中实现的,如何在vue中实现多图联动呢?
下面的是完整的例子
定义2个div
代码语言:javascript复制<div id="chart1"></div>
<div id="chart2"></div>
引入Highcharts和jquery ,因为要用到mouseover事件,方便用jquery获取元素
代码语言:javascript复制import Highcharts from "highcharts/highcharts";
import $ from "jquery";
methods 里面的函数
代码语言:javascript复制 showChart(arr) {
let chartObj = {};
for (let i = 0; i < 2; i ) {
let chartOptions = this.chartOptions;
chartObj["chart0" (i 1)] = Highcharts.chart(
"chart0" (i 1),
chartOptions
);
}
$(".chart-container").on("mousemove", (e) => {
var point, event;
try {
for (var key in chartObj) {
if (chartObj[key].pointer) {
event = chartObj[key].pointer.normalize(e.originalEvent); // Find coordinates within the chartObj[key]
point = chartObj[key].series[0]
? chartObj[key].series[0].searchPoint(event, true)
: null; // Get the hovered point
if (point) {
point.highlight(e);
}
}
}
} catch (err) {
console.log(err);
}
});
$(".chart-container").on("mouseout", (e) => {
var point, event;
try {
for (var key in chartObj) {
chartObj[key].xAxis[0].hideCrosshair(); // 隐藏十字准星线
chartObj[key].pointer.chart.hoverPoints[0].onMouseOut(); // 去掉鼠标状态
chartObj[key].tooltip.isHidden = true;
}
} catch (err) {
console.log(err);
}
});
Highcharts.Pointer.prototype.reset = function () {
return undefined;
};
/**
* 高亮当前的数据点,并设置鼠标滑动状态及绘制十字准星线
*/
Highcharts.Point.prototype.highlight = function (event) {
// event.target.onMouseOver(); // 显示鼠标激活标识
//console.log(event.target);
this.onMouseOver(); // 显示鼠标激活标识
// this.series.chart.tooltip.refresh(this); // 显示提示框
// this.series.chart.xAxis[0].drawCrosshair(event, this); // 显示十字准星线
};
},
上面已实现联动,如果要加上缩放
代码语言:javascript复制 chart: {
type: "spline",
marginLeft: 40,
zoomType: "x",
},
代码语言:javascript复制 xAxis: {
type: "datetime",
dateTimeLabelFormats: {
millisecond: "%H:%M:%S.%L",
second: "%H:%M:%S",
minute: "%H:%M",
hour: "%H:%M",
day: "%m-%d",
week: "%m-%d",
month: "%Y-%m",
year: "%Y",
},
crosshair: true,
events: {
setExtremes: this.syncExtremes,
},
},
syncExtremes是放在methods中
代码语言:javascript复制 // 同步缩放效果,即当一个图表进行了缩放效果,其他图表也进行缩放
syncExtremes(e) {
let thisChart = e.target.chart;
if (e.trigger !== "syncExtremes") {
Highcharts.each(Highcharts.charts, function (chart) {
if (chart && chart !== thisChart) {
if (chart.xAxis && chart.xAxis[0] && chart.xAxis[0].setExtremes) {
chart.xAxis[0].setExtremes(e.min, e.max, undefined, false, {
trigger: "syncExtremes",
});
}
}
});
}
},
注意:setExtremes: this.syncExtremes, 要加this
