I have a feild in my data set caller opendate, (set out DD/MM/YYYY) i have drawn various graphs using a selection on this field 9 a range of dates typically 01/01/2010 - 31/05/2010,but wish to show a comparison line with a previous period.
At this stage I am happy to either do this by entering another set of dates or using the original dates nad minusing a yeaer. I have made the selection using an imput box with a mannualy entered start and endsate and using this to select the dates on an advanced search. Does anyone have any ideas how to acheive this. I have several other selctions made on the data such as company name which need to still apply.
