I'm tracking my average weight via a filemaker database in one field. Two other field serve to calculate a 3-day moving average and an 5-day moving average.
I'd like to see the interaction with these three lines. However, my MA3 and MA5 fields generate their results by grabbing previous records.
Avg Day Weight
+ GetNthRecord (Avg Day Weight ;(Get ( RecordNumber) -1) )
+ GetNthRecord (Avg Day Weight ;(Get ( RecordNumber) -2) )
This makes viewing intersecting lines difficult. MA3 and MA5 need 3 and 5 records, respectively. When I search for a "narrow" date range, like the last 6-14 days, I get a 0 value that skews the entire graph.
How can I force a Y-axis range of ~15 pounds/units instead of letting FM auto-adjust the graph rendering an almost flat line instead?
