After playing around with alternative dimensions/measures I think the exploratory menu is to similar to edit mode. I think that changing dimension/measures need to be "closer" to the user interface, like in Qlikview with the circle arrow.
What's implemented now is a complicated take on circular dimensions, and not intuitive for users. For clarity I think the circle arrow is not that intuitive either.
I would like to have alternative measures in a radio button list that's visible when hovering over the chart. Something like NVD3. Horizontal Multi-Bar Chart - NVD3
- Checkboxes for dimensions and measures. Add or remove as many as you like
- Drag-able column order for tables, like in Qlikview
- More formatting options for cells
