You will get a second window with the imported data table and graph. (This is actually a second
program that is accessible separately from Tracker if you want to do data analysis with existing data
tables.) By the way, if you go back and forth from Tracker to Analysis repeatedly with different
dependent variables, the number of data columns will accumulate. You can control which ones are
used for analysis by dragging the columns to the yellow and green positions as shown here for t and y.
You can control which data sets are displayed with the check boxes at the top of the table.
