Have you ever considered to use a 3rd party library like Qwt or 
QCustomPlot. Both packages are available since years and focus on 
scientific plots.

Being the maintainer of the Qwt package I'm some sort of a biased, but my 
impression is, that the Qt Chart package has never reached a state being 
even close to other solutions. And as I never saw anyone responding to 
related questions on the mailing lists it also does not look like being a 
very actively maintained module.
