This may be too obvious, but what about a scatter plot?

-ttest- sounds more like you are trying to compare means than totals?
Have
you thought about the -total- command proper?
Solorzano Mosquera, Jenniffer
How it is possible to compare between two variables for the same
individual? I'm trying to do a ttest to find differences between
variables constructed from two different data bases for the same unit.
For example, what is the difference between Total of workers for firms
group A based on data base number1 and Total of workers for firms group
A constructed with data base number 2.? I've already did a merge and I
have TotWorkers1 TotWorkers2 variables for the same firms.
