Chart truncating X-axis
Only 2048 values are plotted out of 3241.
(Edit: I removed a Y-axis scaling issue originally reported here and put it in a separate post showing how the problem could more easily be reproduced: forums.filemaker.com/posts/ff7c5f1ef9 )
PolyLine chart with two data sets
One reference table has timestamp field which together with 2 global fields function as foreign key showing 2 data sets from related table
Number of records = 3241
(Averaging in order to get smaller sets is too time-consuming for the user - need to see anomalies)
Data table has timestamp primary key, sampleID primary key, and data value
Timestamp: min = 2011-01-27 00:00; max = 2011-01-29 0:6:00
Temp1: ID = 731; min = 71.9; max = 85.0 (some null entries)
Temp2: ID = 730; min = 65.9; max = 73.4 (some null entries)
Chart shows polylines with X-axis running from timestamp min to max
X-axis displays from record 1 to 2048
Downsample the reference table to skip values. (But we lose sight of any anomalies.)
Thank you for your post.
The current limit for charting of data points is 2048. Another customer on the FileMaker Forum has also encountered this limit, and I have attached your post to the other customer post so consideration for this limit can be increased. See the other customer post at:
