Yeah, though I don't go so negative for it. Was a nice try. And - as you said - simple solution for simple tasks. I think you can append data to series and manipulate them via pointer and call some refresh-routine which behaves pretty much the same as the setRawData - killer-feature of qwt, doesn't it? Allright so far, but everything else really cost me a big deal of time just to find out it wont work. This non-functionallity certainly doesn't feel like what Qt is all about.

I remember a Qt-example (Qt-version 4.something) about how to implement a chart using Qt (I think it was QPainter-example). Promising at first glance. This times I did some real time plotting with high refresh-rates. I clearly remember me rejecting this approach due to the unflexability provided there. Am I wrong or that was QChart's grandma?

Thanks (as always) d_stranz.
