Jor*_*ejo 4 typescript reactjs chart.js react-chartjs-2
我有一个包含以下数据的圆环图组件:
const data = {
labels: ["1", "2"],
datasets: [
{
label: "peers",
data: [1, 2],
backgroundColor: ["#56E2CF", "#56AEE2"]
}
]
};

数据运行正常。这些是选项:
const options = {
legend: {
display: "right"
}
};

甜甜圈成分:
<Doughnut data={data} options={options} />

我尝试使用插件将选项放入 char.js 样式:
const options = {
plugins: {
legend: {
position: "right"
}
}
};

图例移动了,但出现类型错误(仍然没有标题):The types of 'plugins.legend.position' are incompatible between these types. Type 'string' is not assignable to type '"right" | "left" | "top" | "bottom" | "center" | "chartArea" | _DeepPartialObject<{ [scaleId: string]: number; }> | undefined'
const options = {
plugins: {
legend: {
position: "right" as const
},
title: {
display: true,
text: "Title"
}
}
};
