Subject: Pie chart incorrectly use text width to calculate maximum height
Download (untitled) / with headers
text/plain 354b
Chart::Pie takes the maximum of text width and height to calculate the maximum allowed diameter of the pie. This leaves huge vertical margins because obviously, text is usually much wider than it's height. The attached patch does an independent calculation for the two values and only then takes the minimum available space to calculate the diameter.
