363 rows × 8 columns

in Jupyter notebook as shows below: Chart Picture

In pyharm i understand i need to use plt.show() but when i use

plt.plot('pct_day')
plt.show()

an empty plot shows up with no data. I am not sure why is it not plotting the pct_day column?

Empty plot

When i use plt.plot(y='pct_day') i got the following error : TypeError: plot got an unexpected keyword argument 'y'

You should be able to use df.plot(y='pct_day') in pycharm too. Just use plt.show() afterwards... plt.plot('pct_day') do not plot anything because you did not give it any data (df.plot() takes data directly from df)

  • i get the following error when i do `plt.plot(y='pct_day') ` `TypeError: plot got an unexpected keyword argument 'y'` – Slartibartfast Nov 04 '19 at 09:47
  • Is there anyway i would be able to use crosshair to get the data as i move the pointer along the chart? – Slartibartfast Nov 04 '19 at 10:55
