高图-销毁图例后重新绘制/调整图表大小？

Question

I am building several charts on the fly on some of them I remove the legend using chart.legend.destroy(). I have tried chart.reflow() and chart.redraw but the charts do not "refit" themselves and stay the same size as if the legend was still there.

Answer 1

This is a little convoluted.

You can destroy the legend but Highcharts doesn't recognize that it needs to re-adjust for a missing legend. So, you need to set it's display to false . But now Highcharts doesn't realize it's dirty so it won't redraw. So...

    var chart = Highcharts.charts[0];
    chart.legend.destroy();
    chart.legend.display = false;
    chart.isDirtyBox = true;
    chart.redraw(); 

See example here .

Answer 2

You can call setSize like in the example:

if(legend.display) {
            chart.setSize(600,400);
            legend.group.hide();
            legend.display = false;
        } else {
            chart.setSize(500,400);
            legend.group.show();
            legend.display = true;
}
