Highcharts mappa dinamica
In questo capitolo saranno presentati Highcharts mappa dinamica.
Nella sezione precedente che già conosciamo sintassi di configurazione Highcharts. Diamo un'occhiata ad altri Highcharts configurazioni.
Aggiornare secondo grafico
chart.events
metodo load Aggiunto (Grafico evento load) in chart.event. Nel 1000 millisecondi generati casualmente punti dati e generare grafici.
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);
}
}
}

Cliccando il Add Data
chart.events
Aggiungere metodo click (click evento sull'intera area del tracciato grafico verificato) in proprietà chart.event. Questo metodo sulla superficie di terreno grafico aggiungerà un nuovo punto di dati click si verifica.
