You have a valid point as I did not expect plots to be a major performance 
issue. 
I don't think anyone can make performance promises at this point but I would 
also not expect it 
to perform as fast as the current pipeline. On the other hand, being able to 
draw plot charts, 
within Qt Quick was a major reason for adding this API in the first place. 

I also get the feeling that embedding Qt Quick inside Widgets might not be as 
straight forward as I thought,
so I second Samuel's suggestion that just using your existing drawing code with 
a QImage might be the way to go.

I was referring to the labs project in my previous mail. Not official examples.
