I have a straight chart which shows some indicators for particular bank (which i can choose from a list box) over several quarters. I computed some indicators by using Above function in order to include lagged values. It was computed correctly, but now i have to make a chart which summarizes all banks in 4th quarter 2014 and which contains this indicators using lagged values. I can't compute this because above function relates to the values in this summary chart. Any ideas how to solve this problem? Maybe I can somehow compute this indicators in script editor?
