Now this is tricky! You basically have two separate projects: 1. (yours) which is QML2 + Canvas based and probably needs quite a bit more to be a replacement for the "graph-plugin" from sebas [1]. 2. The Qt4 based graph-plugin from sebas with quite a bit of features. Lets get tech details right first: - Both are written with classes/components that use software rendering. (QPainter and Canvas are both software rendering) - Both are not usable for a real animation because of the software rendering. So you'd have to update the frame just once per - say - second to avoid high CPU load. Porting the graph-plugin to Qt5 is likely going to take you a few days depending on how much you work on it. However, you probably also drag in a QWidget dependency while doing so (not 100% sure, please correct me). Then again, extending your plugin to support all the graph-plugin functionality is also going to take you a few days and quite some coordination with probably Sebas. My preference would be QML only as long as it doesn't involve much javascript.
