Mouth breathing vs. mask leaking

[yankees123]

Can someone post some screenshots to show examples of mouth leaking vs. mask leaking?  I know it involves looking at the flow rate but not exactly sure how to differentiate the two.  
thanks

Leakage may be detected if the area in flow rate above the zero line is greater than the area below.  So in the first picture you'll see a mask leak:

   

The next shot shows clearly also a leak, but notice the "flattening" of the flow rate along the zero line:

That's great as I now know what to look for - thank you Mike.
