Chart showing amount of times dates occur

Hi all,
I'm sure there will be some of you shaking your heads in disbelief but I realized this morning that I am absolutely useless with Excel formulas.

I have a user table showing users joined to my site as well as the date they joined etc.

All I want to do is create a chart showing how many users joined on each day.
So I need to get the amount of times a date occurs in the column, displayed next to the specific date.

Can anyone help please?

Thank you in advance.
