Hi Brad,

You will need to process each filter separately in AIJ, save the individual measurements tables, and then merge the two tables so that you can plot them together using Multi-plot_Main->File->"Append table from file as new columns..." to append the new table to an already open table. When asked what to append to the column names for each table, I'd recommend using the corresponding filter names. Then use the "X-data" settings on the Multi-plot_Y-data panel to select different time data column for the different filter bands in the "Y-data" column.
