How to add Error Bars to a Qt Quick ChartView?

Edwin F.

I am trying to create 'Error Bars' in a Qt Quick 2 ChartView. I currently have a line series and need to add minimum and maximum error bars similar to this image here:

I tried to create it hacking a BoxPlotSeries, and that worked okay overlaying a bar chart as seen here:

But adding this to a chart with a LineSeries I cannot control the X location? Anyone ever pull off error bars in QtCharts using QML? Thanks.
