javascript - 如何渲染容器轴的所有值？

Question

我有一个图表，其容器轴包含许多值。在我看来，我必须使用 CSS 属性定义图形的高度。但我不知道高度。当我对高度的预测太小时，一些标签会掉落。我想避免这种情况。不应丢弃任何标签。如何计算所需的高度？

$(document).ready(function() {

    var options = {
        chart: {
            renderTo: 'container',
            type: 'bar'
        },
        title: {
            text: 'Root Login Attempts'
        },
        credits: {
            enabled: false
        },
        legend: {
            enabled: false
        },
        tooltip: {
            enabled: false
        },
        xAxis: {
            type: 'category'
        },
        yAxis: {
            title: {
                enabled: false
            }
        },
        plotOptions: {
            series: {
                animation: false
            }
        },
        series: [{
            data : [

    var chart = new Highcharts.Chart(options);

<div id="container" style="width:100%; height:100%;"></div>

Answer 1

当您使用 CSS 时，系统可以处理动态高度调整:

  #container {
       height:100%;
       width:100%;
       position:absolute;
  }
