You can change the name and data type for a column of data by using the Column Definition tab.
Name
The long name is used in graph axis labels, column headings and menus whenever there is sufficient room. You cannot use quotation marks (“) or the pipe character (|) in the Name.
Short Name
The Short Name is used in graph axis labels, column headings, and menus whenever there is limited room. If you do not enter a Short Name, the first letter of the Name will be used.
Units
The Unit follows the Name in graph axis labels and column headings. If the units that you enter are not the same as a visible line on the active graph window, you will be warned that your column will not be automatically shown in the graph. You can either re-enter units that match a visible line, or click on the y-axis label in the graph window and select your column to be drawn.
You can enter special symbols (including subscripts and superscripts) in all of the above fields from the drop-down menu.
Data Type
You can select different types of data to be collected.
Numeric (sensor and non sensor-based columns) - The experiment time or data point number.
Date (non sensor-based columns only) - The date in day, month, and year in which each data point are collected.
Date and Time (non sensor-based columns only) - The date and time in which each data point are collected.
Time of Day (non sensor-based columns only) - The time of day in which each data point are collected.
Treat as Text (non sensor-based, Events with Entry columns only) - If treat as text is checked, then the entries are merely labels. Example: enter 1, 2, 3, 8 as the entries for EWE. If numeric, then the entered values are actually graphed, and there is a gap between 3 and 8. If text, then the entries are just labels and are plotted equally spaced. As a result, there is no gap between 3 and 8.
Format- When selecting Date, Date and Time, or Time of Day an additional tab appears allowing you to choose the order in which you want the x-axis tick labels displayed. For example, if you set the column as date, the order of the day, months, and year can be arranged to your liking.
