In case it is necessary to display all of this data at once, is it possible to 
offload it to the GPU by displaying it using OpenGL instead of regular widgets? 
You could either use QML and QQuickWidget, or if using C++, there is 
QOpenGLPaintDevice which enables the use of QPainter (and so, 
QPainter::drawText).

Hope this is of use.
