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. For more advanced use cases you can use GridSpec for a more general subplot layout or Figure.add_subplot for adding subplots at arbitrary locations within the figure. We've also changed the tick label colors to match the color of the line plots themselves, otherwise, it'd be hard to distinguish which line is on which scale.

First, lets try to plot a sequence of plots (3 here) by stacking one over the other. For example, the linear_sequence won't go above 20 on the Y-axis, while the exponential_sequence will go up to 20000. Thanks again! Output: If we were to create a multiplot where one plot overlaps over the other one, kind of like what we see when we minimize a youtube video but it still runs in a small window at the bottom corner, then the add_suplplot() function helps in this. This article is being improved by another user right now.
