After rating a page, at the top of the page the previous ratings appear with the default period, in the example last month. Changing this to last 3 months displays a consistent tabular report again (plus explanation for absence of graphs: "Reader ratings over time [purge cache] There is not enough reader feedback data available for graphs at this time.").

Changing to last year or last 3 years makes the tabular report disappear altogether, only explanation for absence of graphs is shown.

The tabular report should be shown in all cases, even if there is insufficient data for graph reports yet.
