To display a variable you enter the variable name, this can be done by typing in the name or by clicking on the Variable button and selecting a variable.
Dataset is the name of the dataset from which to draw the variable, use *1, *2 and so on for access to loaded dataset or leave this blank to get data from the first loaded dataset.
Label is the label that will be used in the first column (row if time is running down). If this is left blank the name of the variable will be used for the label.
Format allows you to determine how the number will appear. Format will be used as a prefix and can contain C language formatting string beginning with a %. Some most common formats would be $ to add a $, %g for scientific notation, and %.0f to show only a whole number (rounded from the underlying number). You can also use %.6g to get 6 digits in scientific notation (the number following the . is the number of significant digits) or %5.2f to get numbers that look like 123.45. Note if you want to see a % sign you need to double it as in %.0f%% to show percentages in whole numbers.
Add adds the content (which must include a variable name) into the list. Once it is in the list you can move it by dragging it to a different position.
