4.4.14 Select or Hide Columns


If you have multiple columns in the active worksheet and you want to select certain columns before plotting or analyzing, you can use the Select dialog.

Data in hidden columns will not be plotted but MAY still be counted in analysis operations. Do not use the Hide button to hide columns and assume that hidden data will be ignored in your analysis.

To open the tool:

  1. Activate the workbook.
  2. Click Edit: Select or Column: Select Columns and open the Select dialog box.
