No chart transparency in Numbers!
I'm trying to create a transparent background to a chart so I can superimpose it over another chart and/or numbers in the Numbers sheet. At the moment, no matter what I do, the background is not transparent. I've selected the chart, set "Background & Border Style" to none and it is still a white background (not transparent).
interestingly, even when I select a colored background, and then make it 100% transparent in the color selector, it is still white and blocks out whatever is behind it.
Did I discover a bug?
I'm on Numbers 3.6.1 on El Capitan
