1) Independent variable (thing you are changing) is usually on the x axis and dependent variable (thing you are measuring) is usually on the y axis. Having the two flipped requires a confusing in-head translation among people who look at graphs regularly.

2) Your plotting software is not plotting your line graph in monotonically changing fashion. This gives zig zags where the graph goes backwards. Addressing #1 could help or plot as a scatter plot ("." option in matplotlib).

3) A detailed description of parameters under the plot would also be nice.

Regardless this is a cool example of bloom filters in action. Thank you!
