How to plot 2 discrete plots (each of a different colour) with stem ?

Hi,

I am trying to use stem to plot a discretised cos and sine waves on a same plot but every point is having a different colour. I want my sine wave points to be of a same colour (e.g. red) and my cos wave points to be of another colour (e.g. blue). Does someone know how to fix this ? Thanks in advance.

plots=[a; b];
time=[t;t]; %Same amount of time for both waves so both have the same vector t
stem(time,graphs);

h = stem(time,graphs) will return a vector of handles. Then set their color using

h(1).Color = 'b'; 
h(2).Color = 'r'; 

If that doesn't solve the problem, please provide more details on the size of "time" and "graphs".
