After plotting all the lines, before displaying the graph, call matplotlib.pyplot.legend() method, which will add the legend to the graph. If we plot it on a logarithmic scale, and the linear_sequence just increases by the same constant, we'll have two overlapping lines and we will only be able to see the one plotted after the first. You can use this to set a line label (for auto legends), linewidth, anitialising, marker face color, etc. For example, if line_1 had an exponentially increasing sequence of numbers, while line_2 had a linearly increasing sequence - surely and quickly enough, line_1 would have values so much larger than line_2, that the latter fades out of view.
