Formula Columns

Top  Previous  Next

Formula columns contain any valid formula.  The main difference is that the contents of the column are constantly updated as data in other columns changes.  They behave more like a traditional spreadsheet.


It is important to note that formula columns slow down the stat tool.  When you change a data point, the stat tool already has to recalculate the statistics view and construct a new graph in the graph view.  Adding formula columns can seriously degrade the program’s performance, particularly on slower machines.
