BoxPlotSeries QML model in C++

Drazz

Hello,

Looking into Qt Documentation of BoxPlotSeries I see just at the beginning:

Instantiates: QBoxPlotSeries

So, if I want to feed that QBoxPlotSeries with data, how can I access it from C++?

ChartView {
        id: boxPlotView

        BoxPlotSeries{
            id: boxPlotSeries

        }
    }

You would expose your data as a C++ table model and use it with VBoxPlotModelMapper :

ChartView {
        id: boxPlotView

        BoxPlotSeries{
            VBoxPlotModelMapper {
                model: myCustomModel // QAbstractItemModel derived implementation
                firstBoxSetColumn: 0
                lastBoxSetColumn: 3
            }
        }
    }

Thank you, that made the job!

Does anyone know how to set labels for BoxPlotSeries using VBoxPlotModelMapper? In the documentation the following is written:

Each box-and-whiskers item contains data starting from row 1. The name of an item is defined by the column header.

However, it is unclear to me what "column header" refers to in this context. I attempted to implement the headerData method, but it wasn't called. Any insights would be appreciated!
