如何使用 Material UI 和 Devexpress 在 React 中创建条形图？-js教程-PHP中文网

Material UI 是一个流行的 CSS 库，我们可以用它来设计 React 应用程序的样式。它包含各种预先设计样式的 React 组件，我们可以通过将它们导入到代码中来直接在应用程序中使用它们。

‘dx-react-chart-material-ui’是Devexpress的一个NPM包，可以连接devexpress的material-ui和‘dx-react-chart’库。 “dx-react-chart”用于创建图表，Material UI 用于设置图表样式。

用户可以执行以下命令在React应用程序中安装Material UI。

npm install @mui/material @emotion/react @emotion/styled

此外，执行以下命令来安装 Devexpress NPM 包。

npm i @devexpress/dx-react-chart

语法

用户可以按照以下语法使用 Devexpress 创建条形图。

<Chart data = {data}>
   <BarSeries valueField = "price" argumentField = "fruit" />
   <Title text = "Fruit price" />
</Chart>

在上面的语法中，我们使用了 DevExpress 的“Chart”、“BarSeries”和“Title”组件。 “Chart”组件显示图表，“BarSeries”组件显示条形图，“Title”组件显示标题。

示例 1（简单条形图）

在下面的示例中，我们从 Material UI 导入了“Paper”组件。此外，我们还从“devexpress”NPM 包中导入了所需的组件。

我们还定义了包含图表数据的 data[] 数组。它包含水果的名称和价格。我们创建一个简单的条形图来比较水果价格。在输出中，用户可以观察条形图。

import React, { useState } from "react";
import Paper from "@mui/material/Paper";
import {
   Chart,
   BarSeries,
   Title,
   ArgumentAxis,
   ValueAxis,
} from "@devexpress/dx-react-chart-material-ui";
import { Animation } from "@devexpress/dx-react-chart";

const data = [
   { fruit: "Apple", price: 150 },
   { fruit: "Orange", price: 250 },
   { fruit: "Banana", price: 100 },
   { fruit: "Mango", price: 200 },
   { fruit: "Grapes", price: 50 },
   { fruit: "Pineapple", price: 90 },
   { fruit: "Watermelon", price: 170 },
   { fruit: "Papaya", price: 120 },
   { fruit: "Guava", price: 80 },
];

function App() {
   return (
      <div>
         <h2>
            Creating the{" "}
            bar chart using the <i>  devexpress NPM   package and material UI </i>
         </h2>
         <Paper>
            <Chart data = {data}>
               <ArgumentAxis />
               <ValueAxis max = {200} />
               <BarSeries valueField = "price" argumentField = "fruit" />
               <Title text = "Fruit Price" />
               <Animation />
            </Chart>
         </Paper>
      </div>
   );
}

示例 2（并排条形图）

在下面的示例中，我们演示了如何创建并排条形图。该数据包含根据颜色的材料名称和价格。

该图表包含单一材料的一系列 3 个条形图，每个条形图代表不同的颜色。我们使用“Barseries”组件为每种材料创建一个条形。此外，我们还设置了组件的标题。

在输出中，用户可以观察并排的条形图，每个条形根据颜色比较不同材料的价格。

import React from "react";
import Paper from "@mui/material/Paper";
import {
   Chart,
   BarSeries,
   Title,
   ArgumentAxis,
   ValueAxis,
   Legend,
} from "@devexpress/dx-react-chart-material-ui";
import { Stack, Animation } from "@devexpress/dx-react-chart";

const chartData = [
   { material: "Aluminium", yellow: 3000, silver: 3200, grey: 2900 },
   { material: "Copper", yellow: 2300, silver: 2700, grey: 1900 },
   { material: "Steel", yellow: 1400, silver: 2100, grey: 1700 },
   { material: "Iron", yellow: 2200, silver: 1700, grey: 2800 },
];

function App() {
  return (
      <div>
      <h2>
         Creating the{" "}
         stacked bar chart using the <i> devexpress NPM package and material UI </i>
      </h2>
      <Paper>
         <Chart data = {chartData}>
            <ArgumentAxis />
            <ValueAxis />

            <BarSeries
               Name = "yellow color"
               valueField = "yellow"
               argumentField = "material"
               color = "#ffd700"
            />
            <BarSeries
               Name = "Silver color"
               valueField = "silver"
               argumentField = "material"
               color = "#c0c0c0"
            />
            <BarSeries
               Name = "grey color"
               valueField = "grey"
               argumentField = "material"
               color = "grey"
            />
            <Animation />
            <Legend position = "bottom" />
            <Title text = "Price of Materials" />
            <Stack />
         </Chart>
         </Paper>
      </div>
