问题：

我创建了一个反应组件，我正在使用图表。我已经构建了一个自定义工具提示组件。我正在用标签检查情况。但它以数字的形式出现在标签上，而不是以我在数据集中提供的名称的形式出现。有人可以帮我解决这个问题吗？

这就是我的代码的外观。

import React, { Component } from "react";
import {
  BarChart,
  Tooltip,
  Bar,
  Legend,
  ResponsiveContainer,
  Cell
} from "recharts";

import { Card, CardTitle, CardBody } from "reactstrap";

import "./SessionDuration.css";

const colors = ["#26a0a7", "#79d69f", "#f9ec86", "#ec983d"];

const data = [
  {
    name: "Page A",
    pv: 2400,
    amt: 2400
  },
  {
    name: "Page B",
    pv: 1398,
    amt: 2210
  },
  {
    name: "Page C",
    pv: 9800,
    amt: 2290
  },
  {
    name: "Page D",
    pv: 3908,
    amt: 2000
  }
];

const CustomTooltip = ({ active, payload, label }) => {
  if (active) {
    return (
      <div className="custom-tooltip">
        <p className="label">{`${label} : ${payload[0].value}`}</p>
        <p className="intro">{getIntroOfPage(label)}</p>
        <p className="desc">Anything you want can be displayed here.</p>
      </div>
    );
  }

  return null;
};

const getIntroOfPage = label => {
  if (label === "Page A") {
    return "Page A is about men's clothing";
  }
  if (label === "Page B") {
    return "Page B is about women's dress";
  }
  if (label === "Page C") {
    return "Page C is about women's bag";
  }
  if (label === "Page D") {
    return "Page D is about household goods";
  }
};

class SessionDuration extends Component {
  render() {
    return (
      <Card className="session-duration-card">
        <CardTitle className="session-duration-card-header">
          Session Duration
        </CardTitle>
        <CardBody>
          <ResponsiveContainer width="100%" height="100%" aspect={4.0 / 5.5}>
            <BarChart
              data={data}
              margin={{
                top: 10,
                right: 5,
                left: 5,
                bottom: 5
              }}
              barGap={10}
            >
              <Tooltip content={<CustomTooltip />} />

              <Bar dataKey="pv" fill="#8884d8">
                {data.map((entry, index) => (
                  <Cell key={`cell-${index}`} fill={colors[index]} />
                ))}
              </Bar>
            </BarChart>
          </ResponsiveContainer>
        </CardBody>
      </Card>
    );
  }
}

export default SessionDuration;

CustomTooltip 中存在未获取标签的问题。所以你需要在下面通过标签给出示例

<Tooltip content={<CustomTooltip label={name} />} />

//Below is small sample of your code that is working fine
