Hello,

I want do an area plot for two sets of data on the same plot. Since there are regions which completely overlap, I would like to introduce transparency in one of them so that I can view the other as well through the 'sheer' layer. How can I do this?

Thanks,
Mika

Mika,

I'm not an expert, but I don't think transparency is possible in MATLAB. What I've done in a similar situation is make a dense scatter plot for the surface / area. This would allow you to leave some space between points, creating a similar effect.

I'll be watching the replies to see if I'm wrong!!

area() returns a vector of hggroup objects. Each hggroup object has one child
object. Each of the child objects is a patch object. You can adjust the
transparency of those patch objects.

Incorrect.
