Apexchart工具提示

Question

我正在尝试在 Y 值后的Apexcharts tooltip中添加％。我正在使用{strong> apexchart 尚未提供官方文档的vue.js。但我知道它能正常工作。这是我到目前为止的内容：

data: function () {
    return {
      apex: null
    }
  },

  // this is the code that handles the chart, there is no official documentation for apexcharts with vue.js but there is with javascript
  //https://apexcharts.com/docs/installation/
  methods: {
      init: function() {
            this.apex = new ApexCharts(this.$refs.barchart, {
            chart: {
                type: 'line',//defines the type of chart
                height:400,
                animations: {
                    enabled: true,
                    easing: 'easeinout',
                    speed: 800,
                    animateGradually: {
                        enabled: true,
                        delay: 50
                    },
                    dynamicAnimation: {
                        enabled: true,
                        speed: 800

                    tickAmount: 6,

                padding: {
                    top: 0,
                    right: 0,
                    bottom: 0,
                    left: 0

            },
            tooltip: {
                enabled: true,
                followCursor: true,
                x: {
                    format: 'dd MMM',
                    formatter: undefined,
                },

                yaxis: {
                    labels: {
                        formatter: (value) => { return val + "%" },
                    },
                },

            },  

            }).render()
      }
  },
mounted() {
      this.init();//mounted makes the chart apear 
  },
  updated() {
      this.init();//updated updates the chart after every change
  }
}

我尝试使用格式化程序来更改结果，但似乎不起作用。

tooltip: {
      enabled: true,
      followCursor: true,
      x: {
          format: 'dd MMM',
          formatter: undefined,
      },

      yaxis: {
          labels: {
              formatter: (value) => { return val + "%" },
          },
      },              
  },

非常感谢您提供任何帮助或参考。

还堆栈不会让我发布顶点图表的新标签，因此这里是官方文档。 Apexcharts

似乎您已将yaxis选项与工具提示标签格式化程序属性混合在一起。

尝试以下代码

tooltip: {
  x: {
    format: 'dd MMM',
    formatter: undefined,
  },
  y: {
    formatter: (value) => { return value + "%" },
  },              
}

此外，还有可以用于ApexCharts的vue.js包装器。
