Apexcharts 工具提示 - 如何为烛台图表添加额外数据?

Apexcharts tooltip - how to add extra data for candlestick chart?

有没有办法将额外的数据传递到数据集并将其显示在 apexcharts 烛台的工具提示中?

我在文档中找不到示例:https://apexcharts.com/docs/options/tooltip/#custom

我想显示如下工具提示:

我终于明白了...

因此,对于 Apexcharts 烛台图表 - 如果您想提供额外的数据并将其显示在工具提示上:

  • 将数据作为描述传递给数据集

    {
      x: new Date(t),
      y: [o, h, l, c],
      description: {
        call_ask1: call_ask1,
        call_ask2: call_ask2,
        call_bid1: call_bid1,
        call_bid2: call_bid2,
        put_ask1: put_ask1,
        put_ask2: put_ask2,
        put_bid1: put_bid1,
        put_bid2: put_bid2,
        expiry1: expiry1,
        expiry2: expiry2,
      },
    }
    
  • 工具提示应具有显示额外数据的自定义功能:

     options.tooltip = {
      custom: function (opts) {
      const desc = opts.ctx.w.config.series[opts.seriesIndex].data[opts.dataPointIndex].description;
      // candlestick standard
      const open = opts.series[opts.seriesIndex][opts.dataPointIndex];
      const high = opts.series[opts.seriesIndex][opts.dataPointIndex + 1];
      const low = opts.series[opts.seriesIndex][opts.dataPointIndex + 2];
      const close = opts.series[opts.seriesIndex][opts.dataPointIndex + 3];
      // Extra tooltip data
      const call_ask1 = desc.call_ask1;
      const call_bid1 = desc.call_bid1;
      const put_ask1 = desc.put_ask1;
      const put_bid1 = desc.put_bid1;
      const expiry1 = new Date(desc.expiry1);
    
      const call_ask2 = desc.call_ask2;
      const call_bid2 = desc.call_bid2;
      const put_ask2 = desc.put_ask2;
      const put_bid2 = desc.put_bid2;
      const expiry2 = new Date(desc.expiry2);
    
      let text = "Open : " + open + "<br>";
      text += "High : " + high + "<br>";
      text += "Low : " + low + "<br>";
      text += "Close : " + close + "<br>";
      text += "<br>";
      text += "Call Ask 1 : " + call_ask1 + "<br>";
      text += "Call Bid 1 : " + call_bid1 + "<br>";
      text += "Put Ask 1 : " + put_ask1 + "<br>";
      text += "Put Bid 1 : " + put_bid1 + "<br>";
      text += "Straddle 1 : <br>";
      text +=
        "Days to exp 1 : " +
        Math.ceil(Math.abs(expiry2 - expiry1) / (1000 * 60 * 60 * 24)) +
        "<br>";
    
      text += "<br>";
      text += "Call Ask 2 : " + call_ask2 + "<br>";
      text += "Call Bid 2 : " + call_bid2 + "<br>";
      text += "Put Ask 2 : " + put_ask2 + "<br>";
      text += "Put Bid 2 : " + put_bid2 + "<br>";
      text += "Straddle 2 : <br>";
      text +=
        "Days to exp 2 : " +
        Math.ceil(Math.abs(expiry2 - expiry1) / (1000 * 60 * 60 * 24)) +
        "<br>";
    
      return text;
    },
    fillSeriesColor: false,
    theme: "dark",
    x: {
      show: true,
      format: "dd MMM yyyy",
    },
    fixed: {
      enabled: true,
      position: "topLeft",
      offsetX: 0,
      offsetY: 0,
    },
