在 plotly express 中，如何重命名轴和图例的名称？ y 轴仅显示为值，图例上的标题是可变的

Question

我的代码：

#启动板颜色编码的成功启动线图

launch_sum = pd.get_dummies(spacex_df,columns=["launchpad"])[["year","launchpad_CCSFS SLC 40","launchpad_KSC LC 39A","launchpad_VAFB SLC 4E","launch_success_True","launch_success_False"]]
launch_sum.rename(columns={"launchpad_CCSFS SLC 40":"CCSFS SLC 40","launchpad_KSC LC 39A":"KSC LC 39A","launchpad_VAFB SLC 4E":"VAFB SLC 4E"},inplace=True)
launch_sum = launch_sum.groupby("year").sum()

px.line(launch_sum, y=["CCSFS SLC 40","KSC LC 39A","VAFB SLC 4E"],title="The Total Annual Attempted Launches")

输出是绘图，但我无法更改图例的 ylabel 和标题。 [1]：https://i.stack.imgur.com/feBYt.png

在布局中更新适当标题的简单案例

import pandas as pd
import numpy as np
import plotly.express as px

launch_sum = pd.DataFrame(
    {
        c: np.random.randint(1, 8, 8)
        for c in ["CCSFS SLC 40", "KSC LC 39A", "VAFB SLC 4E"]
    },
    index=range(2018, 2018 + 8),
)

px.line(
    launch_sum,
    y=["CCSFS SLC 40", "KSC LC 39A", "VAFB SLC 4E"],
    title="The Total Annual Attempted Launches",
).update_layout(yaxis={"title": "some text"}, legend={"title":"column"})
