Solution: Plotting the Grouped Data

Task 1: Flux of calls per day

We now have the column ‘date’ in our data. The emergency department needs to know the flux of calls per day for each reason mentioned in the dataset so that they can take the necessary steps to improve the service.

For this task, find the variation in the number of calls per day for three reasons in the dataset: traffic, fire and EMS.

Hint: You need to group the data for each reason on the date column and call the count().
