Plot pandas-data from Alpha Vantage - pandas

Question

I just installed the alpha_vantage module in addition to pandas, and have gotten the api-key etc. I now want to plot som data regarding a stock.
Written in the module readme (see here) this is how you do it:
from alpha_vantage.timeseries import TimeSeries
import matplotlib.pyplot as plt
ts = TimeSeries(key='YOUR_API_KEY', output_format='pandas')
data, meta_data = ts.get_intraday(symbol='MSFT',interval='1min', outputsize='full')
data['4. close'].plot()
plt.title('Intraday Times Series for the MSFT stock (1 min)')
plt.show()
But when i write just the same in my project whit my own api-key, i get this error:
File "C:\Users\augbi\PycharmProjects\DjangoProsjekt\main\views.py", line 159, in <module>
data['4. close'].plot()
TypeError: tuple indices must be integers or slices, not str
I printed the data, so you can see the format here ( the top line is the result of data.index:
index: <built-in method index of tuple object at 0x0F7CBC28>
( 1. open 2. high 3. low 4. close 5. volume

My own code is here:
ts2 = TimeSeries(key='ALPA_KEY', output_format='pandas')
data = ts2.get_intraday(symbol='AMZN',interval='1min', outputsize='full')
print("index:", data.index)
print(data)
data['4. close'].plot()
plt.title('Intraday Times Series for the AMZN stock (1 min)')
plt.show()
My wish is to plot the "4. Closing" column, and if possible the corresponding times. This data represents stock-prise for amazon for 1 day.
Thank you very much in advance!

Answer 1

I had an Alpah-Vantage APIKEY, so I used the following code to check. It didn't come back with an error as you asked. When I checked the output format, it was not the normal pandas format, but an extended format.

[3440 rows x 5 columns],
{'1. Information': 'Intraday (1min) open, high, low, close prices and volume',
'2. Symbol': 'AMZN',
'3. Last Refreshed': '2021-01-04 19:55:00',
'4. Interval': '1min',
'5. Output Size': 'Full size',
'6. Time Zone': 'US/Eastern'})
From this format, a normal data frame can be obtained with data[0], so a graph can be created. The following is the code to get the graph.
data[0]
1. open 2. high 3. low 4. close 5. volume

print(data)
data[0]['4. close'].plot()
plt.title('Intraday Times Series for the AMZN stock (1 min)')
plt.show()
