Highchart动态创建 - 无法正确呈现

问题描述

我正在用动态函数绘制一幅高画图，它在调用函数之后根本不会渲染。后来如果我调整窗口大小，它会渲染数据？任何具体原因呢？

i am making a highchart drawing using dynamic function, it is not at all rending after the function called. later if i resize the window, it get rendering the data? any specific reason for this?

我的功能：

my function:

var chart;
$(document).ready(function(){

    function randomData(len){
        var arr = [];
        for(var i = 0; i<len;i++){
            arr.push(Math.random())
        }
        return arr;
    }

    var options = {
        chart:{
            renderTo:'graph',
            type:'line'
        },
        title:{
            text:null
        },
        xAxis: {
            plotBands: [{
                    from: 5,
                    to: 6,
                    color: 'yellow',
                    label: {
                            text: 'Yellow'
                    }
            }, {
                    from: 10,
                    to: 11,
                    color: 'green',
                    label: {
                            text: 'Green'
                    }
            }]
    },
        plotOptions:{
            series:{
                animation:false,
                dataLabels:{enabled:true,formatter:function(){return Highcharts.numberFormat(this.y)}}
            }
        }
    }

    chart = new Highcharts.Chart(options);
    var i = 1, s1,s2,s3,s4;

    function createChart(){
        s1 = chart.addSeries({data:randomData(20),name:'Line'+i},false);
    }

    $('#create').click(function(){  createChart() });

})

推荐答案

您需要添加chart.redraw（）;

You need to add chart.redraw();

function createChart(){
    s1 = chart.addSeries({data:randomData(20),name:'Line'+i},false);
    chart.redraw();
}
