This is a screenshot of the battery stats from my phone:
Can I do something similar using Qt Charts ? The closest thing seems to be QHorizontalStackedBarSeries, but it doesn't seem to do the job.

Doubtful, but the implementation of such a chart would be trivial. You are wanting a 1-dimensional chart, where the second dimension is expressed as a color change. As near as I can tell, the Qt Charts are all 2-dimensional, or rotate around a center point.

Nothing is trivial with QtCharts, and I don't kid around.

I was suggesting that it's probably NOT doable in Qt Charts, but that the custom widget to achive the desired result is kind of trivial.

Ah, okay then, my bad. Possible alternatives are QCustomPlot or Qwt if the licenses can be satisfied.

I ended up using QPainter's fillRect() on a QPixmap ... does the job.
Thanks guys :)
