Hardware accelerated realtime graph/chart

[kitestudent]

Hello together,

I want to implement a realtime chart/graph to visualize data. In my special case, the data comes from
a high speed USB device. At the moment, I only need 2D visualisation.

Since the UI should run on several kind of devices I thought that QtQuick2 would be the best choice.

What is the preferred why to implement such a hardware accelerated graph/chart?

• Implement QtQuick addition in C++ with QPainter
• Use custom geometry in the Qt Quick Scene Graph
• Implement Graph in C++/OpenGL and use OpenGL Under QML

That are the ways I know at the moment from looking around in
the examples.

Any other ways?

Best Regards,

You can alsouse the new Canvas item which essentially gives you QPainter functionality in javascript.
