Some of our customers were seeing a problem in the Average Revenue chart, which is part of the Practitioner Performance report. The chart showed values that had nothing to do with the information on the Revenue and Appointments charts from which is derived, or with the summary table at the start of the report.
This happened when the Revenue and Appointments charts had a different number of data points, which could happen if a practitioner happened to not have any invoices issued or appointments scheduled for a given day covered by the report's date filters. The previous calculation didn't take this possibility into account. We have replaced it with one that does, so the chart should look more correct now.
