我正在使用Chart.js,
当我尝试启动代码时,我的devtool控制台会返回我:
Chartjs反应失败的道具类型:无法读取未定义的属性'line'
我怎么可能已经安装了所有依赖项?
这是我的chart.js:
import React, {Component} from 'react';
import {Line} from 'react-chartjs-2';
class Chart extends Component{
constructor(props){
super(props);
this.state = {
chartData:props.chartData
}
}
static defaultProps = {
displayTitle:true,
displayLegend: true,
legendPosition:'right',
location:'City'
}
render(){
return (
<div className="chart">
<Line
data={this.state.chartData}
options={{
title:{
display:this.props.displayTitle,
text:'Largest Cities In '+this.props.location,
fontSize:25
},
legend:{
display:this.props.displayLegend,
position:this.props.legendPosition
}
}}
/>
</div>
)
}
}
这是我的app.js:
import React, { Component } from 'react';
import logo from './logo.svg';
import './App.css';
import Chart from './components/Chart';
class App extends Component {
constructor(){
super();
this.state = {
chartData:{}
}
}
{...}
return (
<div className="App">
<div className="App-header">
<img src={logo} className="App-logo" alt="logo" />
<h2>Welcome to React</h2>
</div>
<Chart chartData={this.state.chartData} location="Massachusetts" legendPosition="bottom"/>
</div>
);
}
}
export default App;
导出默认图表;
任何提示都会很棒, 谢谢
