The test data attached has:

• 3 versions: v1 (archived), v2 and v3 (non-archived)
• 3 issues: one for each version

Each row of the two dimensional statistics gadget displays 1 item of the Y-axis group and the breakdown of the issues returned by X-axis items.

If you choose for the X-axis "Fix For Version (non-archived)", then this breakdown (the columns) correctly does not include any versions which are archived. However, the Total column counts issues which do have archived versions set. See the screenshot for an example.
