Data Point icons in Numbers
Is there any way to import new data point icons in Numbers?
There is a convention in some of the work that I am doing to use particular icons on a specific sort of Chart. Specifically, data from the right hand side is marked with an unfilled circle (easy, it is in numbers) whereas data from the left hand side is marked with a 'x'. There is no equivalent data marker in Numbers.
Is this editable (sic)?
Thanks
