Simple Count events across multiple tables

I have three "EVENTs" tables in the sql database each have different schemas.

Buy Table
Sell Table
Misc Table

I want a simple graph of (the number of these events, timestamp )i.e. each row in the tables is a single event with a timestamp. Is there anyway to do this?

Hi @Shelby
If these tables don't really have anything in common besides being events for different things, then it would probably be easiest to make three questions and then you can make a forth question to join them together.
It's a little difficult to imaging what you could do without understanding the structure or data.
