嗨，伙计们，我一直在做 highcharts ，我陷入了一个逻辑，我找不到一个方法。如果有人能帮助我，这将是非常有帮助的。

HTML格式

<highcharts-chart
       id="container"
       [Highcharts]="Highcharts"
       [options]="chartOptions"
       style="width: 100%; height: 400px; display: block;"
     >
     </highcharts-chart>

TS文件

chartoptions:Highchart.options
      chartOneRender() {
        this.chartoptions = {
        title : {
          text: "Chsart1",
        },
        exporting : {
          sourceWidth: 1500,
          sourceHeight: 300,
          scale: 1,
          enabled: true,
          buttons: {
            contextButton: {
              menuItems: ["viewFullscreen", "downloadCSV", "downloadPNG", "downloadPDF"],
              theme: {
                stroke: '#adaaaa00',
                fill: '#adaaaa00',
              },
              y: 10,
              x: 0,
            },
            custom: this.buttonClicker(optionchart)
          }
        },
          series : [
            {
              name: "s1",
              type: 'column',
              data:  [20,30,40,50]
              visible: true,
            }, {
              name: "s2",
              type: 'column',
              data: [90,98,76,54],
              visible: false,
            }, {
              name: "s3",
              type: 'column',
              data: [67,78,89,54],
              visible: false,
            },
            {
              name: "s4",
              type: 'column',
              data: [89,78,65,45],
              visible: false,
            },
            {
              name: "s5",
              type: 'column',
              data: [78,56,90,98],
              visible: false,
            }
          ],
          }
      }

      buttonClicker(chartOptions: any) {
        var button = {
          y: 10,
          x: -630,
          text: 'Select All',
          theme: {
            stroke: '#000',
            states: {
              hover: {
                stroke: '#298AFC',
                fill: '#fff'
              },
              select: {
                stroke: '#298AFC',
                fill: '#fff'
              }
            }
          },
          onclick: () => {
            this.chartOptions.series.update({
              visible:true
            })
            this.chartOneRender()
        }

        return button
      }

在上面有一个函数称为buttonClicker()我想选择所有的图例，同时点击按钮。如果有人知道任何解决方案，请帮助我。
