EXCEL VBA MACRO EDIT - excel

Question

I need this macro to generate 2 (or more) data columns from 2 (or more) cell references. Currently it only does one data series from one cell reference. The script generates a table and updates the table with a new data entry on each second, then updates a chart using the table data. The cell value is changing in real-time.
This should be a simple fix but I can't figure out the code. I'm out of my league. Any help would be awesome. Maybe somebody can refactor this or at least give me some hints as to what I should do.
