Often the default parameter label that is saved with your data file is not descriptive enough. FCS Express allows you to change the parameter labels that appear on your plots, or use the default ones that exist in the data file.
To facilitate your custom labels, FCS Express provides functionality to create a set of parameter labels than can be saved, and then subsequently loaded for use in other layouts. To create a custom set of parameter labels, from the View Tab, select Parameter Labels, and then Modify Labels. The diagram below shows that we have created the set called "New Parameter Labels", with 4 custom-named parameters.
Once you have created your set of custom parameter labels, you can now select to use them on your plots. On the Axes window below, select the set you want to use from the Parameter Label Set drop-down section. On the Axes screen, you can also change the text formatting (bold, italic, font, size, color, etc.) of the parameter labels.
Below is a plot before the parameter labels were changed (left) and then after (middle and right)
Importantly, parameter label sets do not change your original data. They simply uses the sets you defined instead of the parameter labels in the data file.
