描述
A misalignment issue was observed when resizing on a donut pie chart. The centers of the circles are misaligned after resizing the browser window.(multiple times of resizing are needed to reproduce this issue)
The original nest pie chat:(linke to codepen: https://codepen.io/runqi-han/pen/JjNGQZx)

After resizing the browser n times (n>10)

The issue can be removed by removing textinfo='none' property in the pie chat.
Below is the code used to reproduce the graph(with Dash).
import dash
import dash_design_kit as ddk
import dash_core_components as dcc
import dash_html_components as html
from dash.dependencies import Input, Output
import plotly.express as px
import plotly.graph_objs as go
import numpy as np
import random
app = dash.Dash(__name__)
groups = ["Device Drivers", "Computing Resources", "Peripheral Configuration", "New Devices"]
fig = go.Figure()
holes = [0.2, 0.5, 2/3, 0.75]
domain = [[0.4, 0.6], [0.3, 0.7], [0.2, 0.8], [0.1, 0.9]]
prob = np.random.random(len(groups))
prob = prob/sum(prob)
prob = sorted(prob)
direction = "clockwise"
for i in range(0, len(prob)):
count = random.randint(250, 500)
data = [prob[i], 1 - prob[i]]
soft_type = groups[i]
trace = go.Pie(
hole=holes[i],
domain={"x": domain[i],
"y": domain[i]},
values=data,
direction=direction,
sort=False,
hovertext=[int(count*prob[i]), int(count*(1-prob[i]))],
hoverinfo="label+percent",
labels=[f"Owned {str.capitalize(soft_type)} ({int(count*prob[i])})",
f"Other {str.capitalize(soft_type)} ({int(count*(1-prob[i]))})",
],
textinfo='none',
#textfont_color='white',
textposition='outside',
marker={'line': {'color': 'white', 'width': 5}},
showlegend=True
)
direction = "counterclockwise" if direction == "clockwise" else "clockwise"
fig.add_trace(trace)
fig.update_layout(
legend=dict(
orientation="h",
yanchor="bottom",
y=-0.45,
xanchor="left",
x=0,
itemclick="toggle"
),
showlegend=True,
)
app.layout = ddk.App([
ddk.Row(children=[
ddk.Card(width=100, children=ddk.Graph(figure=fig)),
])
])

app.run_server(debug=True)

调研方向
从提供的 Dash 复现和链接的 CodePen 开始,然后使用 textinfo='none' 的嵌套 pie 轨迹反复调整浏览器大小。比较调整大小前后的圆心,并验证圆心在保持报告的图表行为的同时仍然对齐。
由索引模型根据 Issue 内容生成。
