I have the following data series:
values
Date
2013-01-01 00:00:00 NaN
2013-01-01 01:00:00 0.041702
2013-01-01 02:00:00 0.042505
2013-01-01 03:00:00 0.030535
...
2020-12-30 21:00:00 0.525059
2020-12-30 22:00:00 0.249274
2020-12-30 23:00:00 0.024965
I want to:
2013-01-01 00:00:00
, 2014-01-07 00:00:00
, 2015-01-06 00:00:00
, etc.Plotting this would basically result in a plot with a single line based on about 365 point estimates (ignoring leap years and days with fewer data at the end of the year). I tried starting with pivot tables as suggested here but failed miserably:
df_pv = pd.pivot_table(series.to_frame(), columns=series.index.year)
Exception has occurred: AttributeError 'Series' object has no attribute 'columns'
Any ideas?
It's exactly as you have written down, just a groupby()
not a pivot.
import datetime as dt
import matplotlib.pyplot as plt
fig, ax = plt.subplots(figsize=[10,6])
d = pd.date_range(dt.date(2013,1,1), dt.date(2021,1,1), freq="H")
df = pd.DataFrame({"Date":d,"values":np.random.uniform(0,1,len(d))})
l = df.groupby([df.Date.dt.dayofweek,df.Date.dt.isocalendar().week,df.Date.dt.time]).agg({"values":"mean"}).plot(ax=ax)
l = ax.set_xticklabels(ax.get_xticklabels(), rotation = 90)
