The precise answer depends on the structure of your data and how you set up your chart.
If your chart is based on the current found set, you need only perform a find for the records with the dates that you want to include and then your chart will only be based on that data.
To manually find all the records with dates in 2013, you can enter find mode type in 2013 and click the perform find button in the tool bar.
Thanks, I'll give it a try!
Ok, I've set a button to find with these operators: >=1/1/2013 And this gives me a chart for this year.
This is a big step in the right direction but I can't figure out how to modify the operators to give me a find for, say, the last 60 days. In other words, a chart that would change each day to show the last 60 or 365 days.
To find records for this year, you only have to enter: 2013. You don't need the rest though it works.
You can set up scripted finds that find data using the inequality operator or a date range where a calculation computes that range from the date returned by Get ( CurrentDate ).
See this thread for a number of examples of such finds: Scripted Find Examples
In such a script you can use a calculation such as: ">" & Get ( CurrentDate ) - 60 or you can use: Get ( CurrentDate ) - 60 & "..." Get ( CurrentDate )
Note that the second option won't return the same records as the first if you have records with dates from the future.
