Hello,
I have a chart with the reasonably long expression of:
if( Mod( RowNo(),3 )=0, RangeMax(above(sum(A),0,3))-RangeMin(above(sum(A),0,3)))
Where A is my data field. The purpose of which is to create an S chart (moving range chart).
I want to use the data points for further calculation as a reference line but am unsure how this can be done. E.g Avg(expression), Stdev(expression).
Thanks for the help,
Joshua C
