Hi all,

I have been away from using stata for a couple of years hence am asking a perhaps very stupid question:
How could I create a graph (line) that plots the number of observations of a specific variable over the years? I have to show the number of acquisitions over years, and the acq. variable is a dummy. Data looks like this:
Year acq took place
1991 1
1991 1
.
.
1992 0
1992 0
.
.2018 1
2018 0
.
.Many thanks
