I have managed to create charts in the "Further details", and only there (not in "keycharts") that show the different dimensions. But each dimension is showed in a different chart.
Is there someway to show the different dimensions in the same chart?
In that section of the UI, no. It is hardcoded to display each dimension in it's own chart/section. You would need to use custom charts / the data explorer to combine dimensions and then can place them on dashboards etc...
