How to create graphs / visual representations for frequencies of dates

[N Winters]

I have variables in day/month/year format and also a variable that is just month format (var = month, observations are 1 to 12). How can I plot a simple graph for 'month' representing the frequencies for each month, over a 12 month period?
I basically want to graph the results I get from tabulating the variable 'month', but every plot I've tried requires two variables.
Any help would be appreciated.

Well, there is -histogram, discrete-, and also -graph bar-.

I'm not sure if I understood how's the data displayed. That said, perhaps - tsline - would fit your needs.
