Assignment 10 - plt.plot not fitting line to data properly

[drbigshog]

Hi,
I am running into an issue for Task 2 part b and c where the line I am fitting to the dependent variable is not functioning properly.

Here is my code, and here is a screenshot of the result. The scatter plot appears fine, but the line isn't working as it did in part a).

This happens in both questions but here is part b):

formula_2 = 'co2_per_capita ~ income'
res2 = smf.ols(formula=formula_2, data=world_data_2014).fit()

sns.scatterplot(x='income', y='co2_per_capita', data=world_data_2014)
plt.plot(world_data_2014.income,results.fittedvalues)

I looked online, and some sites suggested sorting the data, but I'm curious why this code doesn't work as expected. Thanks!

Solved it, should have res2 and res3.fittedvalues instead of resultds
