React 如何使用Material UI和Devexpress创建条形图

Material UI是一个流行的CSS库，我们可以用它来为React应用程序添加样式。它包含各种预先样式化的React组件，我们可以直接在代码中导入并使用它们。

‘dx-react-chart-material-ui’是一个Devexpress的NPM包，可以将material-ui和devexpress的’dx-react-chart’库连接起来。’dx-react-chart’用于创建图表，Material UI用于为图表添加样式。

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

另外，请执行以下命令安装Devexpress NPM包。

npm i @devexpress/dx-react-chart

语法

用户可以按照以下语法使用Devexpress来创建柱状图。

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

在上述语法中，我们使用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（简单的条形图）

在下面的示例中，我们从Material UI导入了‘Paper’组件。同时，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。我们创建了一个简单的条形图来比较水果的价格。在输出中，用户可以观察到条形图。

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>
   );
}
export default App;

示例2（并排柱状图）

在下面的示例中，我们演示了如何创建一个并排柱状图。数据包含了材料的名称和根据颜色的价格。

这个图表包含了一个材料的三个柱状图，每个柱状图代表了不同的颜色。我们使用了“Barseries”组件来为每个材料创建一个柱状图。此外，我们还设置了组件的标题。

在输出中，用户可以观察到并排柱状图，每个柱状图按照颜色比较不同材料的价格。

import React from "react";
import Paper from "@mui/material/Paper";

   Chart,
   BarSeries,
   Title,
   ArgumentAxis,
   ValueAxis,
   Legend,

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>
   );
