Numbers - How modify chart?
I've got a numbers spreadsheet with a chart that was done awhile back.
I've been trying to add more rows and another column(series).
I've researched it but cant seem to get what I need
I'm hoping that a good hearted person will offer to take a look at some screen shots and tell me what I'm doing wrong.
Thanks
