Help needed for Matplotlib in Stata

[Wee Yang Ng]

Hi,

I am using Stata 17 and was using some python codes to plot some bar charts. Below is my code:

python:
import os
os.chdir("C:/Users/ngwee/OneDrive/INSEAD RA work")
import pandas as pd
df = pd.read_csv('start_date.csv')
import matplotlib.pyplot as plt
x = df['rec_start_dates']
y = df['unrate_rec_start']
plt.bar(x,y)
plt.ylabel('Monthly Unemployment Rate(seasonally adjusted)')
plt.xlabel('Months')
plt.title("Unemployment at Recession Start dates")
plt.bar(x, y, color='blue')
plt.savefig("myplot.png")
plt.show()
end

However, when I run the codes, I am greeted with an error message:

---------------------------
StataSE-64
---------------------------
This application failed to start because it could not find or load the Qt platform plugin "windows"
in "".

Reinstalling the application may fix this problem.
---------------------------
OK   
---------------------------

May I know what do I have to install in Stata to make Matplotlib work? I had run other codes except for Matplotlib and they run smoothly so I am not sure how to make it work.

Any help in this area would be appreciated. Thanks!

I don't know but the Stata version of the problem would seem to yield to twoway bar quite easily.

This is probably a python issue: to side-step the problem try using a different backend for matplotlib adding

matplotlib.use('TKAgg')

after import matplotlib. If you need Qt you may have to reinstall packages - google the error message and you will find suggestions.
