Plot issue (maybe using set and gca)

Hey guys, here is the code that I have:
stem(Tim,Var1,'MarkerSize',0,'Color','k'); hold on;
stem(Tim,Var2,'MarkerSize',0,'Color','g');
stem(Tim,Var3,'MarkerSize',0,'Color','r'); hold off;
datetick('x','mm/dd');
set(gca,'YTickLabel',{0; 1; 2; 3;})
So for a specific length of time, Var1 = 1, Var2 = 2, Var3 = 3. I expect my Y axis to represent this, and the stem for each Var should rise to the associated value.
However, when I plot, this is not the case. Here is what actually happens:
Any help or advice on this issue would be much appreciated!
EDIT*** For this plot's time period, Var2 should be the only one showing.

Because all Vars are defined as absolute time ranges. It just turns out that for the time period that I have plotted in the x axis, Var2 is defined.
Think of the Vars as "events" that occur during absolute time. I just want a record of those events.

Var3 does not occur within the time period that I have plotted

I have thought about it a little more. I think this has to do with my YTickLabel. Basically, I have to make sure that the label corresponds with the value of Var.
Does anyone know how I can make each YTick correspond with the value of Var1 - 3?
