To plot multiple line plots in Matplotlib, you simply repeatedly call the plot() function, which will apply the changes to the same Figure object: Without setting any customization flags, the default colormap will apply, drawing both line plots on the same Figure object, and adjusting the color to differentiate between them: Now, let's generate some random sequences using NumPy, and customize the line plots a tiny bit by setting a specific color for each, and labeling them: We don't have to supply the X-axis values to a line plot, in which case, the values from 0..n will be applied, where n is the last element in the data you're plotting. I want to plot the mean of different metrics by sweeping the threshold values (IOUth). 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.
