react,Chart-编程知识

react,Chart

一、基础图：https://ant-design-charts.antgroup.com/ Ant Design Charts

1. 首先要下载@ant-design/charts，然后在页面中添加如下柱状图代码:

import React from 'react';
import { Column } from '@ant-design/charts'const DemoColumn: React.FC = () => {const data = [{type: '分类一',sales: 38},{type: '分类二',sales: 52},{type: '分类三',sales: 61},{type: '分类四',sales: 145}, {type: '分类五',sales: 48}, {type: '其他',sales: 38}]const config = {data,xField: 'type',yField: 'sales',label: {// 可手动配置 label 数据标签位置// position: 'middle',// 'top', 'bottom', 'middle',// 配置样式style: {fill: '#FFFFFF',opacity: 0.6}},xAxis: {label: {autoHide: true,autoRotate: false}},meta: {type: {alias: '类别'},sales: {alias: '销售额（万）'}}}return <>antdCharts<Column {...config} /></>;
}
export default DemoColumn;

效果如下：

2.然后实现下这个案例区间曲线面积图在柱庄图的基础上替换相关配置，代码如下：

import React from 'react';
import { Area} from '@ant-design/charts'const DemoColumn: React.FC = () => {const config = {data: {type: 'fetch',value: 'https://assets.antv.antgroup.com/g2/range-spline-area.json',transform: [{type: 'map',callback: ([x, low, high, v2, v3]) => ({ x, low, high, v2, v3 }),},],},xField: 'x',yField: ['low', 'high'],shapeField: 'smooth',style: {fillOpacity: 0.5,fill: '#64b5f6',lineWidth: 1,},axis: {y: { title: false },},scale: {x: { type: 'linear', tickCount: 10 },},point: {yField: 'v2',shapeField: 'point',sizeField: 2,},line: {yField: 'v3',style: {stroke: '#FF6B3B',},},};return <>Area<Area {...config} /></>;
}
export default DemoColumn;
