In the 2D plot options, click the "Add Data" button to open a selection window.
Two options are possible:
-Select a curve in an existing table from the "Base Viewer"
-Select another curve from your computer (csv file).
For the second choice "another curve", after the csv selection, a pop-up opens, presenting the data in a table form. Click on the row of table to select a curve (or a column if you are in the vertical view selection).
