标签列表未显示在图表中? [英] Label list is not showing in recharts?

问题描述

问题:

我已经使用图表创建了条形图.我在条形图中使用了labelList组件.但是它没有显示我的标签.这就是我组织条形图的方式.

I have created a bar chart using rechart. There I am using labelList component inside my bar chart. But It is not showing my label. This is how I organized my bar chart.

import React, { Component } from "react";
import { bindActionCreators } from "redux";
import { connect } from "react-redux";

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

import {
  BarChart,
  Tooltip,
  Bar,
  ResponsiveContainer,
  Cell,
  XAxis,
  YAxis,
  CartesianGrid,
  LabelList
} from "recharts";

import "./MostPopularTenChannels.css";
import { get_device_width } from "../../../actions";

const data = [
  {
    name: "A",
    uv: 15.64
  },
  {
    name: "B",
    uv: 8.19
  },
  {
    name: "C",
    uv: 6.66
  },
  {
    name: "D",
    uv: 5.9
  },
  {
    name: "E",
    uv: 4.11
  },
  {
    name: "F",
    uv: 3.99
  },
  {
    name: "G",
    uv: 3.64
  },
  {
    name: "H",
    uv: 0.188
  },
  {
    name: "I",
    uv: 0.171
  },
  {
    name: "J",
    uv: 0.15
  }
];

const COLORS = [
  "#26a0a7",
  "#c5e587",
  "#cdd477",
  "#d2cb6e",

class MostPopularTenChannel extends Component {

    this.getDeviceWidth = this.getDeviceWidth.bind(this);
  }

  componentDidMount() {
    this.getDeviceWidth();
    window.addEventListener("resize", this.getDeviceWidth);
    window.addEventListener("load", this.getDeviceWidth);
  }

  getDeviceWidth() {
    this.props.get_device_width();
  }

  render() {
    let yaspect = 5.0;
    let height = 0;
    let t_count = 0;
    let left = 10;
    if (this.props.device >= 1024) {
      height = 55;
      t_count = 2;
      left = -25;
    }

    if (this.props.device >= 1666) {
      yaspect = 7.25;
      height = 90;
      t_count = 3;
      left = 10;

推荐答案

声明酒吧时，添加道具isAnimationActive并将其设置为false，如下所示:

When you declare your Bar, add the prop isAnimationActive and set it to false, like this:

<Bar isAnimationActive={false} dataKey="uv" fill="#8884d8" minPointSize={15}>
   {data.map((entry, index) => (
     <Cell key={`cell-${index + 1}`} fill={COLORS[index]} />
   ))}
   <LabelList
     dataKey="uv"
     position="top"
     angle="90"
     content={<CustomizedMostPopularLabel />}
   />
</Bar>
