Don't use excel often and the boss has asked to produce some charts for him, this is relating to phone calls. The data that's been provided has many thousands as below. This represents the date and time of the phone calls. I have never done this before and am lost. How do I produce a graph out of this data showing calls per day. I'd need some formula that would consider the day i.e. 01/10/2018 and the number of calls taken that day, which would be all the calls under the same date as below. How would I do this?

01/10/2018 16:50
01/10/2018 16:45
01/10/2018 16:54
