If the data source settings for your chart base the chart on data from your found set, A pair of global date fields can be set up for this with a script that performs a find and/or constrains the found set of records using the dates in these two fields.
Here is a thread with many examples of scripted finds that use data from global fields: Scripted Find Examples
If your data source settings chart related data, the global field data can be used as match fields in the relationship to further filter down the data used in the chart.
And it's also possible with delimited data to use the data in such fields--an ExecuteSQL query could incorporate the data in a WHERE clause for example.
Great, that thread is a real eye opener about global fields. I have tried this with my chart, and it appears to be on the right track, but any idea why it is adding the total sum of all days in specified range, and apply that amount to each bar on the chart?
For instance, before running script: Day 1=$10,000, Day 2=$15,000
After running script: Day 1=$25,000, Day 2=$25,000
Did you sort your records after constraining your found set or performing the find? To get a sub total for each point on your graph, the data has to be sorted to group them by day.
THANK YOU!!!, that was it.
