My data is in weeks, e.g. week 1-53 in 2012 and I just want to display these 53 weeks in 2012. I imported as you suggested, 2001-2053 as years. Then I play the trendline, it displayed fine. Then I changed the 2001-2053 back to weeks 1-53 in editor, when I chose trendline and mouse over any of the region, it gave me error message:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
When I click continue, this message showed again.
Could you let me know how to deal with this? I am using StatPlus now.
