如何通过DOM容器访问Highcharts图表? [英] How can I get access to a Highcharts chart through a DOM-Container?

问题描述

当我向div容器渲染高图表时，如何通过div-container访问图表对象?

When I render a highcharts-chart to a div container, how can I get access to the chart object through the div-Container?

我不想使图表变量成为全局变量.

I don't want to make the chart variable global.

        var chart = new Highcharts.Chart({
            chart: {
                renderTo: "testDivId",
                                ...

我想像这样(伪代码)在上面的上下文之外访问图表，以调用函数:

I want to access the chart outside of the context above like this (pseudocode), to call functions:

var chart = Highcharts.Chart("testDivId"); //access from id
chart.redraw();

推荐答案

Highcharts 3.0.1

用户可以使用highcharts插件

Highcharts 3.0.1

Users can use the highcharts plugin

var chart=$("#container").highcharts();

Highcharts 2.3.4

对于版本2.3.4和更高版本，请从 Highcharts.charts 数组中读取，图表的索引可以从<div>

Highcharts 2.3.4

Read from the Highcharts.charts array, for version 2.3.4 and later, the index of the chart can be found from the data on the <div>

 var index=$("#container").data('highchartsChart');
 var chart=Highcharts.charts[index];

所有版本

通过容器ID在全局对象/地图中跟踪图表

All versions

Track charts in a global object/map by container id

var window.charts={}; 
function foo(){
  new Highcharts.Chart({...},function(chart){  
      window.charts[chart.options.chart.renderTo] = chart;
  });
}

function bar(){
  var chart=window.charts["containerId"];
}
