Ranges predefined and named minimal and maximum to automatically format statistics out of expected ranges in the table editor. Ranges can be set in Preferences, under the Tools section.
Ranges are predefined for ease but are completely editable for customization. The two button at the top allow you to add a new range or delete an existing range.
To add a new range, click on the Add new range button and a new line will appear. Simply, double click within the line to edit it.
To delete a range, highlight the line in the table and click the button Remove selected.
Ranges can be used in conjunction with heatmaps.
