Plot data along line

Hi,

I am new to COMSOL but learning. I think that there must be a simple solution to this, but I haven't been able to find it yet.

I am trying to find values from my simulation along a like that I have drawn. I placed a boundary probe but this doesn't apear to be the correct option since I am only able to get a single value. I would like all values along the line. Is there a way to measure this and get values along the entire line?

All help is greatly appreciated.

Thanks, Josh
