Hi,
Is it possible to create bar chart with error bars with QtCharts ? Or to find bars position of a QChart?
I want to modelize the standard deviation of each bar..
I already tried to find the position of each bar with "scene" argument of QChart but I didn't success.
Thanks for your help.

do you have a visual example? You could just add 2 more series with the lower and upper confidence level on the same x and y axis...

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.

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

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.
