  I first downloaded a local copy of the  .csv  file
  using  

wget URL  

  Then the python code below following the plot parameters
  shown in your  imgur.com  image which was executed
  in a jupyter notebook 

# it_covid.py ---

import pandas as pd
import seabornas sns
import numpy  as np
import matplotlib.pyplot as plt

df = pd.read_csv( 'data/somministrazioni-vaccini-latest.csv' )

plt.figure( figsize = ( 20 , 10 ) )

plt.xticks( rotation = 70 )

sns.lineplot( 
x= "data_somministrazione" , 
y= "prima_dose" , 
data = df , 
hue  = "nome_area" , 
ci   = None )


plt.show()

# ---

  The resulting plot doesn't seem to be cluttered
  as the one that you posted

Don't have the original email, hence replying this way.

Pretty much what he said...
Parse the dates. Oh and you generally don't need the dance with urllib, pandas
can do that for you.

```
data_url = 
r"https://github.com/italia/covid19-opendata-vaccini/blob/master/dati/somministrazioni-vaccini-latest.csv?raw=true;

df = pd.read_csv(data_url, parse_dates=True, index_col="data_somministrazione")

plt.figure(figsize=(15,10))
plt.xticks(rotation=70)
sns.lineplot(x=df.index, y="prima_dose", data=df, hue="nome_area", ci=None)
```

trying to do some dayaviz with Italian Covid Open Data ( 
https://github.com/italia/covid19-opendata-vaccini/ )


here's how I pull my data:

import sys
import urllib.request
import pandas as pd
import ssl
ssl._create_default_https_context = ssl._create_unverified_context

URL = 
"https://github.com/italia/covid19-opendata-vaccini/blob/master/dati/somministrazioni-vaccini-latest.csv?raw=true; 



with urllib.request.urlopen(URL) as url:
     df = pd.read_csv(url)


One of my diagrams came out screwed up today, and I am having a hard 
time understanding what went wrong:

Any ideas?

Thanks



I don't think this is the cause of your problem and in addition I don't
know about pandas. In any case you send pandas some records that contain
the date in string format and this gives the alphabetic continuity but
if the data contained time holes, these would not be represented in your
graph. Maybe you should add an intermediate step and convert strings
dates to datetime format before you create the chart (but perhaps pandas
takes care of this. I don't know this).

cheers.
