Highcharts dynamische Karte
In diesem Kapitel werden wir Highcharts dynamische Karte einführen.
Im vorigen Abschnitt wissen wir bereits Highcharts Konfigurationssyntax. Schauen wir uns die anderen Konfigurationen Highcharts aussehen.

chart.events
Hinzugefügt Load-Methode (Chart Ladeereignis) chart.event Eigenschaft. In 1000 Millisekunden zufällig Datenpunkten erzeugt und Diagramme zu erzeugen.
chart: {
events: {
load: function () {
// 图表每秒更新一次
var series = this.series[0];
setInterval(function () {
var x = (new Date()).getTime(), // 当期时间
y = Math.random();
series.addPoint([x, y], true, true);
}, 1000);
}
}
}

Das obige Beispiel Ausgabe lautet:
Mit einem Klick auf die Daten hinzufügen
chart.events
Fügen Sie Click-Methode (klicken Ereignis auf das gesamte Diagramm Grundstück aufgetreten ist) in chart.event Eigenschaft. Dieses Verfahren auf dem Gebiet Grafik Plot fügt ein neuer Datenpunkt Klick auftritt.
chart: {
events: {
click: function (e) {
// 获取点击坐标和数据项
var x = e.xAxis[0].value,
y = e.yAxis[0].value,
series = this.series[0];
// 添加点击的坐标
series.addPoint([x, y]);
