Question

我试图隐藏标签并在鼠标移开时更改边框宽度，并在鼠标移出时将图形返回到其原始状态。＆＃34;未捕获的TypeError：无法读取属性＆＃39;状态＆＃39;未定义＆＃34;继续展示，我不知道该怎么做。

        var showLabel = function () {
            var options = myChart.options;
            options.xAxis[0].labels.enabled = true;
            options.plotOptions.series.borderWidth = 0;
            myChart = new Highcharts.Chart(options);
        };  
        var hideLabel = function () {
            var options = myChart.options;
            options.xAxis[0].labels.enabled = false;
            options.plotOptions.series.borderWidth = 3;
            myChart = new Highcharts.Chart(options);
        };


        // Make monochrome colors and set them as default for all pies

        Highcharts.getOptions().plotOptions.bar.colors = (function () {
            var colors = [],

                // up with a much brighter color
                colors.push(Highcharts.Color(base).brighten((i - 3) / 7).get());

您应该使用axis.update和series.update动态更新图表，而不是在每个鼠标事件上重新创建图表。

获取图表容器而不是系列也会更好，因为你想要更改图表和系列。

示例：https://jsfiddle.net/aythcvop/

$(function() {
  var showLabel = function(chart) {
    chart.xAxis[0].update({
      labels: {
        enabled: true
      }
    }, false);
    Highcharts.each(chart.series, function(series) {
      series.update({
        borderWidth: 0
      }, false);
    });
    chart.redraw();
    //options.xAxis[0].labels.enabled = true;
    //options.plotOptions.series.borderWidth = 0;
    //myChart = new Highcharts.Chart(options);
  };
  var hideLabel = function(chart) {
    chart.xAxis[0].update({
      labels: {
        enabled: false
      }
    }, false);
    Highcharts.each(chart.series, function(series) {
      series.update({
        borderWidth: 3
      }, false);
    });
    chart.redraw();
    //options.xAxis[0].labels.enabled = false;
    //options.plotOptions.series.borderWidth = 3;
    //myChart = new Highcharts.Chart(options);
  };


  // Make monochrome colors and set them as default for all pies
