我在工作中有一个案例,我想使用饼图,为此我使用Chart.js(用react-chartjs-2库作为 Package 器)。
我希望在画布的左右两边都有填充,但由于某种原因,在这种情况下,我总是得到顶部填充,即使我专门键入top:有没有人知道为什么会发生这种情况,以及什么是一种只有左右填充的方法?
const options = {
layout: {
padding: {
left: 100,
right: 100,
top: 0,
}
}
}
代码如下所示,同时添加了代码沙盒:

import "./styles.css";
import { Box } from "@mui/material";
import { Chart as ChartJS, ArcElement, Tooltip, Legend } from "chart.js";
import { Pie } from "react-chartjs-2";
ChartJS.register(ArcElement, Tooltip, Legend);
export const data = {
labels: ["Red", "Blue", "Yellow", "Green", "Purple", "Orange"],
datasets: [
{
label: "# of Votes",
data: [12, 19, 3, 5, 2, 3],
backgroundColor: [
"rgba(255, 99, 132, 0.2)",
"rgba(54, 162, 235, 0.2)",
"rgba(255, 206, 86, 0.2)",
"rgba(75, 192, 192, 0.2)",
"rgba(153, 102, 255, 0.2)",
"rgba(255, 159, 64, 0.2)"
],
borderColor: [
"rgba(255, 99, 132, 1)",
"rgba(54, 162, 235, 1)",
"rgba(255, 206, 86, 1)",
"rgba(75, 192, 192, 1)",
"rgba(153, 102, 255, 1)",
"rgba(255, 159, 64, 1)"
],
borderWidth: 1
}
]
};
const options = {
layout: {
padding: {
left: 100,
right: 100,
top: 0,
}
}
}
export default function App() {
return (
<Box>
<Pie data={data} options={options} />
</Box>
);
}
