Figure T2.6 Insert Histogram (Step 5)
Note that when inserting the histogram, you were not prompted to select a file. This is because FCS Express uses the most recent data file when adding a new plot. You are only prompted to select a data file if no data files have been opened, or you select the When creating a new plot, always display the selection dialog preference from the FCS Express User Options (described below).
Plots can also be inserted using the Data→Save/Load→Open command.
