Plotting stop length
If you were stopped for a particular violation, how long might you expect to be detained?
In this exercise, you'll visualize the average length of time drivers are stopped for each type of violation. Rather than using the violation
column in this exercise, you'll use violation_raw
since it contains more detailed descriptions of the violations.
This exercise is part of the course
Analyzing Police Activity with pandas
Exercise instructions
- For each value in the
ri
DataFrame'sviolation_raw
column, calculate the mean number ofstop_minutes
that a driver is detained. - Save the resulting Series as a new object,
stop_length
. - Sort
stop_length
by its values, and then visualize it using a horizontal bar plot. - Display the plot.
