SETBLANKLABEL
SETBLANKLABEL can be used to replace blank row or column categories with custom text.
Syntax
SETBLANKLABEL.<ROW/COLUMN>(VALUE)
Arguments
VALUE - Pass the custom value to use instead of blank categories.
Example
SETBLANKLABEL.ROW('row_label')
SETBLANKLABEL.COLUMN('col_label')

Notice how the blank row and column categories are replaced with the custom text "DESC". The buttons use the SETBLANKLABEL script internally.
