Spacing for Charts

[carsten.h]

I have a charting solution where I need to place various charts side-by-side. Currently I am just using a grid-layout which take a QChartView with a QChart inside. Basically I want to eliminate the yellow spots in the setup !

I already setting any margins and contentsMargin to zero. I also tried negative top/left plus larger sizes. Anyway no effect here.

I would assume there some kind of padding/spacing within the QChart ?
