How to create a broken Axis in a bar chart of QChart

[mameo]

I'm using the Qt5.4.0.
I am currently developing software to create a bar graph in QChart.
I want to express the Broken Axis.
I want to create a figure below in QChart.

Wavy line and I think that it can be created in QGraphicsItem.
But I do not know how omitted a number of memory of the Y-axis.

Please tell me someone.
Thank you.
