QwtPlot image file without QApplication

We have a server with no user interface and minimal graphics support that we would like to use qwtPlot to general plots from streams of data without using qApplication.

Is there a way to generate a png or jpeg from qwtPlot without QApplication?

All of the examples I have been through use a QPixmap or a QImage to create an image file using a QPainter. Thus, the QApplication object is needed and will not work on our server for generating the desired plot image files from our raw data.

Thanks,
Steve

No and even worse: you always need at least an invisible plot widget.
