As the author of KQtQuickGraphs I think both components are sufficiently different to \
co-exist, as they serve different purposes.
The plotter componednt (as the name suggests) seems to provides realtime \
visualization over a trend of a continiously changing value. Drawing performance is \
really important, as the data may always change, flexibility not that much.
The components in KQtQuickGraphs aim to be a more general approach to data \
visualization, used in KDE Edu (currently KTouch and Artikulate) to illustrate the \
learner's progress.
Also the plotter is Qt5 ready and uses OpenGL for its drawing needs, so currently it \
is in a better shape than KQtQuickGraphs.
So +1 from me.
