I had a very similar problem with a program I am writing, and this Accepted Answer did not work for me, using Matlab 2017b. I modified the code slightly, and wanted to share my solution, as the accepted answer is no longer completely correct, with Matlab 2017b, at least, as the following error is thrown when setting 'MarkerSize' to zero:
Error using matlab.graphics.chart.primitive.Stem/set
Error setting property 'MarkerSize' of class 'Stem':
Value should be a finite number greater than 0
An appropriate fix to this is setting the 'Marker' property to 'none', as described below:
figure
x = 0:25;
y = [exp(-.07*x).*cos(x);exp(.05*x).*cos(x)]';
h = stem(x, y);
set(h(1),'MarkerFaceColor','blue','Marker','none')
set(h(2),'MarkerFaceColor','red','Marker','none')
Now, I used the exact code provided above. I would not format the block of code this way; I like plots to be contained in a single function call, if possible. This was just to show the concept.
Example of output:
Now, I just looked at this output, seeing as we only see one stem plot. Well, the example functions given are bad examples, as the 'blue' function is always smaller than the 'red' function.
Here is a better example:
figure
x = 0:25;
y = [exp(-.07*x).*cos(x);0.075*sqrt(x)]';
h = stem(x, y);
set(h(1),'MarkerFaceColor','blue','Marker','none')
set(h(2),'MarkerFaceColor','red','Marker','none')
Example of output:
This demonstrates that the code is actually doing what you want, for both stem plots.
The same job could be done with one line of code, and this is how I would solve the question:
stem(x, y, 'Marker','none')
