我正在使用在图表中插入数据时会提供数据的海图,但我想动态插入数据

是否可以将这些数据动态添加到highcharts中,而不是自定义数组中?是否可以使用每个循环动态插入数据?有什么方法可以使用表或另一个数组来动态地使它?由于我是海图新手,所以我不知道如何使用它。 预先感谢

您可以使用updatesetData方法将序列/数据添加到已经存在的图表中:

$.getJSON( "...", function( data ) {
  chart.series[0].setData(data);
});

// OR

$.getJSON( "...", function( data ) {
  chart.update({
    series: [{
      data: data
    }]
  });
});

API参考:

https://api.highcharts.com/class-reference/Highcharts.Chart#update

https://api.highcharts.com/class-reference/Highcharts.Series#setData


或在数据加载完成后创建图表:

$.getJSON( "...", function( data ) {
  Highcharts.chart('container', {
    series: [{
      data: data
    }]
  });
});

您还可以使用Highcharts数据模块:https://www.highcharts.com/docs/working-with-data/data-intro,例如从CSV获取数据。
