Probably you can just add a Box Whiskers series with just the whiskers http://doc.qt.io/qt-5/qtcharts-boxplotchart-example.html

Good idea but I need a grouped bar chart for a scientific article.

[NuttinGo]

No idea ?

[VRonin]

reimplementing the paint of the chart is of course a solution but painful

[NuttinGo]

UP!
I don't have solution.

[NuttinGo]

UP! Please :)

I want to veer off-topic slightly, but I think it's a shame that it's currently impossible to create scientific graphs using Qt. Error bars are essential for plotting functions or displaying data points.

I hope that the Qt team will eventually enable scientists and data scientists to fully utilize this framework.

Thank you to everyone at Qt 👍👏. I'm seriously considering purchasing a commercial license just to support your future efforts.

@MElectronVolt VTK may have some options for scientific graphs. VTK was started for rendering of scientific data. Qt was not. Good news is you can use mix Qt with VTK.
