How do you plot a regression line in Matplotlib?
How to plot a linear regression line on a scatter plot in Python
- x = np. array([1, 3, 5, 7]) generate data. y = np. array([ 6, 3, 9, 5 ])
- plot(x, y, ‘o’) create scatter plot.
- m, b = np. polyfit(x, y, 1) m = slope, b=intercept.
- plot(x, m*x + b) add line of best fit.
How to plot points in a Matplotlib diagram?
Draw two points in the diagram, one at position (1, 3) and one in position (8, 10): You will learn more about markers in the next chapter. You can plot as many points as you like, just make sure you have the same number of points in both axis. Draw a line in a diagram from position (1, 3) to (2, 8) then to (6, 1) and finally to position (8, 10):
