# Adjusting the bin numbers

Let's take our first steps away from the default number of bins with our histograms. We'll start by building a histogram of the percentage of the speed a driver is traveling over the limit for each citation. This is calculated as `((speed - speed_limit) / speed_limit)*100`

.

Plot percentage over the speed limit as a histogram with the number of bins set to 40. While you're at it, set the `alpha`

to `0.8`

. You're entirely on your own with this one, no scaffolding.
