QVBarModelMapper does not update BarChart on Model change

[oliverleo]

Hi,

I am using QVBarModelMapper to show a BarChart. I provided my own implementation of QAbstractTableModel.
But the BarChart does not update, when the data in the TableModel changes allthough dataChanged() is emitted.
What do I have to do to automatically update the BarChart, when the model changes?

can you post your custom model code? the setData part in particular

I aldready fixed it. The dataChanged() call was wrong. Thanks for your respond
