        buttons: {
            contextButton: {
              x: 0
            }
          }
      },

推荐答案

该按钮使用 highcharts-chart 键将图表保存在localStorage中.例如，您可以在刷新浏览器后使用它保留一些绘制的注释.

The button save a chart in localStorage under highcharts-chart key. You can for example use it to keep some drawn annotations after refresing a browser.

存储以下项目:

• 注释
• 指标(带有yAxes)
• 标志

您可以通过以下方式获取选项:

You can get the options in the following way:

const savedOptions = localStorage.getItem(['highcharts-chart']);
