Example of chart disappearing

There seems to be a major problem when rendering a pie chart based on a series with one very large value and one very small (e.g. 99.99 and 0.01). When rendering the chart with GDI, with no shadow and no 3D, the entire pie disappears.

We have encountered the problem in TeeChart for ReportBuilder (which only seems to support GDI and not GDI+) but it's the same when placing a TChart component on a Delphi form (and set GDI as renderer). Is there anyway to switch to GDI+ in TeeChart for ReportBuilder? If not, I guess this is a rather serious bug that should be fixed.

What exactly does "RESOLVED FIXED" mean? In which version(s)?
