图例在右侧展示时，并且图例的字数比较多。当下次数据导入时图例的字数较少，会导致饼图往右偏移。这个能否优化一下呢。不管字数多少都不影响饼图的位置。

### 问题描述

图例在右侧展示时，并且图例的字数比较多。当下次数据导入时图例的字数较少，会导致饼图往右偏移。这个能否优化一下呢。不管字数多少都不影响饼图的位置。
代码：
import { Pie } from '@antv/g2plot';

const data =[
{
"type": "分类一",
"value": 10,
"colorField": "JASJA难道你"
},
{
"type": "分类二",
"value": 20,
"colorField": "ASSJAJSJAJSJASJAJSJ"
},
{
"type": "分类三",
"value": 30,
"colorField": "JAJDSJAJD"
},
{
"type": "分类四",
"value": 40,
"colorField": "JAJSJA29392"
},
{
"type": "分类五",
"value": 50,
"colorField": 500
},
{
"type": "分类六",
"value": 60,
"colorField": 600
},
{
"type": "分类七",
"value": 70,
"colorField": 700
}
];

const piePlot = new Pie('container', {
appendPadding: 10,
data,
angleField: 'value',
colorField: 'colorField',
radius: 0.9,
label: {
type: 'inner',
offset: '-30%',
content: ({ percent }) => `${(percent * 100).toFixed(0)}%`,
style: {
fontSize: 14,
textAlign: 'center',
},
},
interactions: [{ type: 'element-active' }],
});

piePlot.render();

Start by reproducing the supplied TypeScript Pie example in G2 with long and short right-side legend labels. Inspect the legend and pie layout calculation, then verify that changing label lengths between data imports does not move the pie horizontally.
