有沒有辦法用plotly或python創建條形圖可視化，其中y軸是24小時范圍，x軸是所有作業日？

我正在嘗試創建一組人的作業時間的可視化（理想情況下是 plotly，因為我想合并一個下拉欄，允許用戶在美國的時區之間切換并相應地調整時間）。x 軸是作業日，y 軸是 24 小時范圍，條形圖將垂直向下（顯示某人在周一至周五上午 7 點至下午 3 點作業）并且可以與其他人的作業時間重疊（我知道我需要使用不透明度引數）。

到目前為止，我已經嘗試了很多東西，最接近的是以下代碼：

import plotly.graph_objects as go
import pandas as pd

# Initialize figure
fig = go.Figure()

week_days = ["Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday"]

# Add Traces
fig.add_trace(
    go.Bar(x=week_days,
           name="Nicole",
           #line=dict(color="#33CFA5")
          ))
#fig.update_yaxes(strftime("%H:%M"))

fig.update_layout(
    updatemenus=[
        dict(
            active=0,
            buttons=list([
                dict(label="None",
                     method="update",
                     args=[{"visible": [True, False, True, False]},
                           {"title": "CSI Work Hours",
                            #"annotations": []
                           }]),
                dict(label="MT",
                     method="update",
                     args=[{"visible": [True, False, False, False]},
                           {"title": "MT",
                            #"annotations": high_annotations
                           }]),
                dict(label="PT",
                     method="update",
                     args=[{"visible": [False, False, True, True]},
                           {"title": "PT",
                            #"annotations": low_annotations
                           }]),
                dict(label="HT",
                     method="update",
                     args=[{"visible": [True, True, True, True]},
                           {"title": "HT",
                            #"annotations": high_annotations   low_annotations
                           }]),
            ]),
        )
    ])

# Set title
fig.update_layout(title_text="CSI")

fig.show()

#create plot with days of week as x-axis, 24hr range as y-axis
fig, ax = plt.subplots(figsize=(15,15))
#ax.plot_date(start_date, end_date, ydate=True, xdate=False)

#number of days in week 7, set to x-axis to display all week days
l = range(0,7)
week_days = ["Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday"]

# reformat axis ticks to only show hour/min on y-axis; label x-axis w/ week days
from matplotlib.dates import DateFormatter
from matplotlib.axis import Axis
ax.yaxis.set_major_formatter(DateFormatter('%H:%M'))
ax.yaxis.set_major_locator(HourLocator())
ax.invert_yaxis()
#ax.set_yticks(t)
ax.set_xticks(l)
ax.set_xticklabels(week_days)

對于實際資料點，我嘗試為每個人或每個時區創建字典，但我無法弄清楚如何為資料點繪制串列。

person1_hrs_dict = {'Monday' : [7,8,9,10,11,12,13,14,15],
              'Tuesday' : [7,8,9,10,11,12,13,14,15],
              'Wednesday' : [7,8,9,10,11,12,13,14,15],
              'Thursday' : [7,8,9,10,11,12,13,14,15],
              'Friday' : [7,8,9,10,11,12,13,14,15],
              'Saturday' : 0,
              'Sunday' : 0
             }
MT_hrs_dict = {"weekdays":["Monday", "Tuesday", "Wednesday",
 "Thursday", "Friday", "Saturday", "Sunday"],
"csi team": ["person1","person2",etc],
"work hours": []}
#I don't think MT_hrs_dict would work since some people work weekends and have some weekdays off.
#I think I'm overcomplicating it or maybe creating text document might be easier?

這是一個非 Plotly 解決方案，只是 Matplotlib。

讀者可以理解如何在代碼中輕松計算正確的條間距和位置。

• 做你所描述的很簡單。已完成您所描述的作業，構建了一個包含星期幾、開始時間、作業時間、員工的資料框
• 這成為一個簡單的柱狀圖中，其中，星期幾是X軸和Y軸一間酒吧，演出開始時間和作業時間

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

employees = list("ABC")

df = pd.DataFrame(
    itertools.product(
        pd.date_range("18-oct-2021", periods=7, freq="D").values, employees
    ),
    columns=["date", "employee"],
).pipe(
    lambda d: d.assign(
        start=np.random.randint(1, 10, len(d)),
        hoursworked=lambda d: np.random.randint(3, 10, len(d)),
        dow=d["date"].dt.strftime("%a")
    )
)

px.bar(df, x="dow", y="hoursworked", base="start", color="employee", barmode="group")

資料框樣本

資料框構建 - 更簡單的語法

df = pd.DataFrame(

    ),
    columns=["date", "employee"],
)
df["start"] = np.random.randint(1, 10, len(df))
df["hoursworked"] = np.random.randint(3, 10, len(df))
df["dow"] = df["date"].dt.strftime("%a")
