高图图表重绘方法不刷新图表

Question

我很想知道为什么按钮2在这个例子中不起作用

在这个jsfiddle示例中,附加到按钮1的"更新"方法正常工作,但在我的原始代码中,"更新"也无效.它显示错误:"对象#没有方法'更新'"

$(function () {
    var options= {
        chart: {
            renderTo: 'container',
            height: 400
        },
        xAxis: {
            categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
        },
        
        series: [{
            data: [29.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4]        
        }]
    };
   
    var chart = new Highcharts.Chart(options);
    buttonhandle1();
    buttonhandle2()
});

function buttonhandle1(){
    $("#b1").click(function(){
            var chart = $('#container').highcharts();
            chart.yAxis[0].update({
                min:0,
            max: 5,
            tickInterval : 1,
        });
    });
}

function buttonhandle2(){
    var chart = $('#container').highcharts();
    $("#b2").click(function(){
        chart.yAxis[0].min= 0;
        chart.yAxis[0].max= 5;
        chart.yAxis[0].tickInterval = 1;
        chart.redraw();
    });
}

<script src="http://code.highcharts.com/highcharts.js"></script>
<div id="container" style="min-width: 400px; height: 400px; margin: 0 auto"></div>
<button id="b1"> button 1</button>
<button id="b2"> button 2</button>

Answer 1

因为当你使用时,你chart.redraw()也应该将isDirtyflag 设置为true

chart.yAxis[0].isDirty = true;
