Batch plot with column offset mode means plot columns in source graph with column offset.

Column Offset: specify the offset value from source column to target column
Number of Offsets: specify the number of offsets

for example, source graph is scatter plot with Y column D&E, column offset = +2 means new plot columns are F&G, column offset =-2 means new plot columns are B&C.

if column offset=+2 and number offsets=3 for source graph with B&C means new plot columns are D&E, F&G, H&I

when user has many books with same column structure, and make a graph using columns in different books. if user want to make plot using other column of all these different workbooks, batch plot with column offsets can handle this well.
