I've built a report which includes some pie charts. Everything works great as expected. Pie charts are built to show Aircraft Launches per aircraft, revenues per aircraft, and hours flown per aircraft. Each pie has the "Percentages" box ticked.
Launches and revenues are number fields and the hours flown is a duration field taken from our flight logs as a calculation, time_down - time_up
The launches and revenue PIE Charts are both fine. The Hours flown Pie (The duration attribute) shows a blank box with "No Data Available" in the middle.
I should add at this point that the text line details correctly calculate and show the hours flown - so I'm just talking about the PIE CHART
Checking the log viewer I can see the attributes being populated. The Hours_This month has an entry that says Hours_Flown=Bas.com.duration [very big number - looks like seconds or even milliseconds]
Is this one a bug?
