数据集为 7 天。即 7 * 24 行。如何绘制上面数据集的图形。

hr_slot on the X axis : (0-23 hours)
loaction_point on Y axis : (location_point)
and each day should have different color on the graph: (Day1: color1, Day2:color2....)

考虑先旋转数据:

# Create normalized date column
df['date'] = df['time slot'].dt.date

# Pivot
df.pivot(index='hr_slot', columns='date', values='location_point').plot()

替代方法改为使用 pandas.crosstab :

(pd.crosstab(df['hr_slot'],
             df['time slot'].dt.date,
             values=df['location_point'],
             aggfunc='sum')
 .plot())
