Axis expressions
An axis expression defines how you want a variable to appear when you tabulate it in UNICOM Intelligence Reporter - Survey Tabulation. An axis expression can apply to a categorical, numeric, text, date, or Boolean variable. For example:
For a single response variable that stores answers to a question that asks respondents to provide a rating for a product, an axis expression might assign a factor to each category and special elements to show the mean value and the standard deviation.
For a multiple response variable that stores answers to a question that asks respondents to select responses from a list that has both positive and negative categories, an axis expression might define special net elements to show the number of respondents who chose one or more positive responses and one or more negative responses.
For a numeric variable that stores respondents' ages as a numeric value, an axis expression might define elements that band the ages into age groups, and a special element to show the mean value calculated from the raw numeric values.
For a text variable that stores respondents' addresses, an axis expression might define elements based on city names or postal codes.
For a Boolean variable, an axis expression might define two elements, one for True values and one for False.
In some data sets, axis expressions might be predefined (stored in the metadata) for all or some of the variables. To create axis expressions in UNICOM Intelligence Reporter - Survey Tabulation, select a variable, and then click Variables > Edit. The Edit Variable dialog opens, which has simple and script views. For numeric variables, there is a third view that makes banding easy. For more information, see Working with variables.
