List Check
List checking validates the data in a column. Set up the column to accept only individual numbers that you
specify. List checking is useful when you want to specify how to order the data in your graphs or plots.
• Use the buttons to add new values, change, or reverse the order of values, and remove values.
• Once a list check is set on a column, the cursor changes to when positioned over the cells. If you
try to enter a value not included on the validation list, a warning message appears.
• To see a menu of acceptable values, right-click a cell and select List Check Values. You can select the cell
value from the menu instead of typing it into the cell.
• From the data table, modify the list check by clicking next to the column name in the Columns
panel.
To turn off list checking:
1. From the data table, right-click the column name in the Columns panel.
2. Select Validation > No Checking.
Missing Value Codes
Use missing value codes to specify column values that should be treated as missing. For example, sometimes
the value 99 is used as a placeholder to represent missing values, or perhaps several values are used to
represent different types of missing values.
Value Labels
Use value labels to show a label in the data table instead of a value. A label appears for each instance of the
value. You can show the original values by double-clicking a label within a cell.
• Type the value that you want to assign a label to in the Value box.
• Type the label that you want to appear in the Label box.
• To use ranges, click Allow Ranges then specify the lower and upper values.
Tip: To assign a label to missing values, enter a period (.) for the lower bound and leave the upper bound
empty. To assign a label to all other values, enter three periods (...) for the lower bound and leave the upper
bound empty.
• Add, change, or remove labels.
Note the following tips:
• To turn off value labels in the data table without deleting the value labels that you have set up, deselect
Use Value Labels.
