The data is from measurements performed on different times and different days. For example, the linear_sequence won't go above 20 on the Y-axis, while the exponential_sequence will go up to 20000. Overall trend and difference between the days (colors) being the most important things to note and also the easiest to visualize (for the trend you just observe the distribution of the lines. I have a bunch of plots as the one reported below. The first way is when we want to add a single or main title to the plots or subplots, then we use suptitle() function of pyplot module.
