Removing chart borders in Numbers 3.6
In Numbers 3.6, charts now appear with a mandatory box around them. This is terrible design for quantitative information. I can't figure out how to turn off that box. The leading contender – Background and Border Style in the Chart sidebar – turns off the axes to the chart but the border box remains.
Anyone know how to remove this box? It makes Numbers charts look like the amateurish, janky Excel charts. It is ruining Numbers as a tool for best practices information design and presentation.
