Qt Charts duplicating data ?
I am discovering the Qt Charts module, and thinking about using it, but looking at the documentation I am wondering : Is there any way to plot data which is not actually stored inside QAbstractSeries instance ? I am searching something equivalent to QwtSeriesData
This is quite an important feature for us because we have a big amount of data to plot, and we do not want to duplicate these data in memory. We also need to present the same data in other formats, eg in tables.
Regardless of the answer, thanks a lot for releasing Qt Charts in GPL !
