react-chart-2 <"Line" 不是注册控制器。>
react-chart-2 <"Line" is not a registered controller.>
目前,我正在编写一个代码,当通过 React 接收到输入时,它会自动将输入值绘制到图表中。我正在尝试使用 usestate 添加保存的图表进行测试,但我无法继续处理错误 <"Line" is not a registered controller.>.
有什么方法可以解决这个错误吗?
代码如下:
import {CreatChart} from './WidgetCRUD'
import Chart from 'chart.js/auto'
import {Radar,Line,Pie,Doughnut,PolarArea, Bar} from 'react-chartjs-2'
const options =
{
responsive: true,
scales:
{
yAxes:
[
{
ticks:
{
beginAtZero: true,
},
},
],
},
}
const data =
{
labels: ['1', '2', '3', '4', '5', '6', '7' , '8', '9','10'],
datasets: [
{
type: 'line',
label: 'Dataset 1',
borderColor: 'rgb(54, 162, 235)',
borderWidth: 2,
data: [30, 9, 24, 50,-20,20, 17, 45, 49],
}
],
}
const main = () =>
{
const [createChart, setCreateChart] = useState([])
setCreateChart(<Line data = {data} options={options} style={{ position: "relative"}}/>)
return (
<div>{createChart}</div>
)
}
这是我的代码,因此您需要根据自己的代码进行调整,首先您需要从 chart.js 导入所需的所有内容,具体取决于您需要的图表,我使用的是折线图
import {
Chart as ChartJS,
CategoryScale,
LinearScale,
PointElement,
LineElement,
Title,
Tooltip,
Legend,
TimeScale,
ChartOptions
} from 'chart.js';
import { Line } from 'react-chartjs-2';
然后你需要注册元素:
ChartJS.register(
CategoryScale,
LinearScale,
PointElement,
LineElement,
TimeScale,
Title,
Tooltip,
Legend
);
