xpoints = ypoints = plt.xlim() plt.plot(xpoints, ypoints, linestyle='--', color='k', lw=3, scalex=False, scaley=False)
Here is what the above code is Doing:
1. We’re creating a list of x-values that we want to plot.
2. We’re creating a list of y-values that we want to plot.
3. We’re plotting the x-values and y-values.
4. We’re setting the x-axis limits to be the same as the y-axis limits.
5. We’re plotting a line that has the same slope as the line we plotted in step 3.
