Introduction
This article describes how to create stand-alone footers and customize them.
A standard footer output is included when creating charts and tables which can be manually edited:
However, you can create a stand-alone footer that can be further customized and allow for:
- The footer text remains customized if the underlying data is updated (ex, custom base size description).
- The footer text will update automatically if the underlying data is updated or filters are applied, as opposed to manually typing "Base is 300" in a standard footer, which will not update automatically, even if the base size changes.
- More screen real estate by removing repeated footers if you have multiple charts on a page.
Requirements
You will need:
- At least one visualization, chart, or table on your page.
-
A Complete Data Variable. This needs to be a variable which has missing values for any observations that are not in the sample that you are describing.
- If you want to report the sample size for the entire data set, an ID variable is a good idea.
-
In some cases, you may need to construct a variable which has the correct cases for the Complete Data Variable. You can read more about how to construct a Complete Data Variable here.
Method
- From the toolbar, click Anything > Page Design > Sample Size Description.
- In the Complete data variable field (shown in the object inspector) select a variable. Whatever variable is selected will be used to compute the sample size, based on all responses without missing values.
-
You will then get an output showing "Base: total sample; sample size: nnn". OPTIONAL: You can customize the wording and the formatting from the object inspector in the Initial text, Total sample description, Sample size description, and Final text fields.
- Tick Automatic, if not already ticked. This ensures that whenever the data changes, including applying a filter, the sample size description will update accordingly.
- OPTIONAL: To change the appearance of the text that is displayed:
- Click on the sample size description widget.
- Go to Properties > APPEARANCE in the Object Inspector and update the background and/or font color, font size, font style, and add a border as desired.
