I have two vectors of data and I've put them into matplotlib.scatter(). Now I'd like to over plot a linear fit to these data. How would I do this? I've tried using scikitlearn and np.scatter.

In matplotlib, if you want to draw a horizontal line with full width simply use the axhline() method. You can also use the hlines() method to draw a full-width horizontal line but in this method, you have to set xmin and xmax to full width.
import numpy as np from numpy.polynomial.polynomial import polyfit import matplotlib.pyplot as plt # Sample data x = np.arange(10) y = 5 * x + 10 # Fit with polyfit b, m = polyfit(x, y, 1) plt.plot(x, y, '.') plt.plot(x, b + m * x, '-') plt.show()
