Finally, we can apply the same scale (linear, logarithmic, etc), but have different values on the Y-axis of each line plot. Let's use NumPy to make an exponentially increasing sequence of numbers, and plot it next to another line on the same Axes, linearly: The exponential growth in the exponential_sequence goes out of proportion very fast, and it looks like there's absolutely no difference in the linear_sequence, since it's so minuscule relative to the exponential trend of the other sequence. Now, let's plot the exponential_sequence on a logarithmic scale, which will produce a visually straight line, since the Y-scale will exponentially increase. 5 Answers Sorted by: 45 There are several different ways to do this.
