我的一个 React 页面上有一个条形图。它从从另一个页面传递的props中获取数据。我有一个条形图,显示了三个不同的数据。一个显示“正确”,另一个显示“不正确”,最后一个显示“总计”。我想让每个条的颜色都不同。我曾尝试使用 Cell 功能,但无法使其正常工作。我也尝试更改每条数据的名称,但没有成功。不幸的是,Recharts 的文档并不多。有人有任何想法吗?
import React from 'react';

ResponsiveContainer, BarChart, Bar, Cell, XAxis, YAxis, CartesianGrid, Tooltip, Legend,
} from 'recharts';
export default class GameChart extends React.Component {
constructor(props) {
super(props);
this.state = {
axes: [
{ primary: true, type: 'ordinal', position: 'left' },
{ position: 'bottom', type: 'linear', stacked: true }
],
series: {
type: 'bar'
},
chartData: [
{
name: 'Correct',
total: 0,
},
{
name: 'Incorrect',
total: 0,
},
{
name: 'Total',
total: 0,
},
],
chartLayout: {
title: 'Math Game Results',
yaxis: {
showticklabels: false
},
}
}
}
componentDidUpdate(prevProps) {
if (prevProps.chartData.totalCounter !== this.state.chartData[2].total) {
let tempState = this.state;
tempState.chartData = [
{
name: 'Correct',
total: this.props.chartData.correctCounter,
},
{
name: 'Incorrect',
total: this.props.chartData.incorrectCounter,
},
{
name: 'Total',
total: this.props.chartData.totalCounter,

];
this.setState(tempState);
}
}
