Standard Deviation Found Set Layout...?
Just wondering if some of you may have an opinion on which approach to take when making a layout to both calculate and graph the standard deviation of a found set of records. What I need to accomplish is to make a layout in which a user may select a group of data by its name (say "SampleType1, SampleType2, SampleType3"). After the user selects said "SampleType" from a dropdown, the records of that type must be found and listed in a portal. From there I wish to have the standard deviation calculated and graphed. Every time a user selects a different "SampleType" the aforementioned process repeats and the new information replaces the old. Not a sort answer I know, but any guidance would be much appreciated.
