I will when I finish it :) For out of the box examples, there's QtCharts. I don't quite like it as it uses QGraphicsItem engine, which is CPU bound. But my early work with QtQuick 2 is very promising. Btw. in my experience, the most resource hungry part is not the rendering itself but handling data. SC seems to hold tick data in memory (my impression based on writing a plugin, tick data is available as an in-memory array). So a lot of the stuff is calculated live in memory. The database story has evolved a lot over the last few years, it's possible these days to store it in a database and precalculate a lot without significant delays. Check out Clickhouse. It's amazing.
