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. >>> This should be ideal for graph plotting within Qt Quick as is >>> already demonstrated by the examples. >> >> I checked a Qt 4.8 snapshot, but was not able to identify what example it >> is ? >> I was referring to the labs project in my previous mail.
