This report displays hit statistics for individual conversions that were logged as part of the selected A/B test during the specified time interval. You can select the conversion that you wish to evaluate from the Conversions drop‑down list.
Each item in the graph represents a single unit of time according to the selected report type (an hour, day, month etc.). The data logged for the chosen conversion is categorized according to the page variants defined for the given A/B test. This allows you to easily determine which variant generated the most conversion hits of the selected type.
Please see the Web analytics Overview topic for details about the general actions available for reports.
Further information about A/B testing can be found in Developer's Guide -> Modules -> Website optimization -> A/B testing.
