Multiple fields on x-axis

Multiple fields on x-axis

Hi 
I'm new to Analytics. 

I'm trying to create a chart that counts the number of leads on the y axis.

Along the x axis I would like to display multiple fields
ie. 
We have 4 date fields.  I want to display the count of leads where a particular date field is not empty as one column and then replicate that for each date field.  

Is this possible?

Thanks, Bianca
