How to set transparency of stem plot (alpha) - is it even possible?

19 views (last 30 days)
Hi everyone,
I am using the stem function and would like to set the transparency (or alpha) to values other than 1 for certain data points.
The code I am using is basic:
s = stem(x,y);
I have tried setting s.Color(4) = 0.5 but s.Color(4) is non-existent.
I have also tried: alpha(s,0.5)but I get the error:
Warning: The alpha command is not compatible with the specified objects.
Is there any way of setting the transparency in stem plots?
thank you

Hi Jack,
Kindly refer to the following example in which I am Adding the transparency by setting the "FaceAlpha" property to a value between 0 (completely transparent) and 1 (completely opaque) to the stem plot.
data = [2 4 6 7 8 7 5 2]; %input data
stem(data) %creating stem plot of data
dim2 = [.74 .56 .1 .1]; %specifying the dimensions and position of the rectangle
For more information regarding adding the transparency using stem function, kindly refer to the following documentation:
I hope this answer helps you.
