Extra Columns

Any columns in the spreadsheet after the Orientation, Quantity, Traverse, Set, Distance, X, Y, Z, and Persistence columns, are referred to as Extra Columns, and can be used to store any other quantitative or qualitative data that the user wishes to record.

Adding / Removing Extra Columns

• Extra Columns are added with the Add Column option in the Edit menu or toolbar.
• Extra Columns are deleted with the Remove Column option in the Edit menu or toolbar.

Extra Column Data

The data in Extra Columns may be either:

• Quantitative (numeric measurements) or
• Qualitative (alphanumeric labels or mnemonics)

The data in a single column should be of a consistent type (i.e., Quantitative or Qualitative), to ensure correct interpretation of data when using the Symbolic Plot, Chart and Filter Data options.

Number of Extra Columns

Any number of Extra Columns may be added to the spreadsheet.

Extra Column Titles

Extra Column titles are displayed in UPPERCASE LETTERS, to help differentiate them from the Orientation, Quantity, Traverse, Set, Distance, X, Y, Z, and Persistence columns.

However, the Quantity, Traverse and Set columns may appear in UPPERCASE, if they have been saved as Extra Columns while using the Save Processed File or Filter Data options.
