I'm using recent (3.2.1) version of Stacked Column 2d chart. I get strange results when having negative values. You can see in the example that when having just 2 categories, one series with values 20 and -20, the limits on X-axis range is (-44,66) which seems for me far too wide. I know it is a bit degenerated example, but it is only to emphasise the problem.
What is the algorithm (what should I expect) for generating axis limits ?
