使用Plotly结合Streamlit时X轴消失的问题求助

大家好，我最近碰到一个头疼的问题：单独用Plotly绘制散点图时，图表显示完全正常，但把同样的图表放到Streamlit里展示后，X轴居然凭空消失了！想请教下有没有大佬能帮忙分析下原因？

单独使用Plotly的情况 #

单独运行Plotly代码时，图表的X轴、Y轴都正常显示，效果如下：

import plotly.graph_objects as go
import plotly.express as px 
import pandas as pd


data = {'x': [1.5, 1.6, -1.2],
        'y': [21, -16, 46],
        'circle-size': [10, 5, 6],
        'circle-color': ["red","blue","green"]
        }

# Create DataFrame
df = pd.DataFrame(data)
fig = px.scatter(
    df,
    x="x", 
    y="y", 
    color="circle-color",
    size='circle-size'
)


fig.update_layout(
    {
        'xaxis': {
            "range": [-100, 100],
            'zerolinewidth': 3, 
            "zerolinecolor": "blue",
            "tick0": -100,
            "dtick": 25,
            'scaleanchor': 'y'
        },
        'yaxis': {
            "range": [-100, 100],
            'zerolinewidth': 3, 
            "zerolinecolor": "green",
            "tick0": -100,
            "dtick": 25
        },
        "width": 500,
        "height": 500
    }
)
fig.show()

结合Streamlit使用的情况 #

把同样的图表集成到Streamlit后，X轴就不见了，代码和效果如下：

import streamlit as st
import plotly.graph_objects as go
import plotly.express as px 
import pandas as pd


data = {'x': [1.5, 1.6, -1.2],
        'y': [21, -16, 46],
        'circle-size': [10, 5, 6],
        'circle-color': ["red","blue","green"]
        }

# Create DataFrame
df = pd.DataFrame(data)
fig = px.scatter(
    df,
    x="x", 
    y="y", 
    color="circle-color",
    size='circle-size'
)


fig.update_layout(
    {
        'xaxis': {
            "range": [-100, 100],
            'zerolinewidth': 3, 
            "zerolinecolor": "green",
            "tick0": -100,
            "dtick": 25,
            "scaleanchor": 'y'
        },
        'yaxis': {
            "range": [-100, 100],
            'zerolinewidth': 3, 
            "zerolinecolor": "red",
            "tick0": -100,
            "dtick": 25
        },
        "width": 500,
        "height": 500
    }
)
event = st.plotly_chart(fig, key="iris", on_select="rerun")

event.selection

有没有朋友知道为什么在Streamlit里展示时X轴会消失呢？我对比了两段代码的布局设置，除了X轴和Y轴的零线颜色调整了，其他参数（比如范围、刻度间隔、scaleanchor这些）都是一样的，但就是看不到X轴了，实在搞不懂哪里出问题了😢
