This article describes how to create stand-alone footers and customize them. The Sample Size Description updates based on new data updates and filters applied. You may want to use a sample size description widget when:
- You have a page with lots of outputs and you want to reduce clutter by deleting their individual footers.
- Your output doesn't have a footer generated for it automatically (as-is for visualizations without tests).
A Complete Data Variable. This needs to be a variable which has missing values for any observations that are not shown on the page. Normally this will just be a variable used in the outputs, but you can choose any variable depending on what you want to describe.
If you want to report the sample size for the entire data set, an ID variable is a good idea.
If your outputs have varying base sizes, you may need to construct a variable which has the correct cases for the Complete Data Variable and customize the sample size widget using R code.
- From the toolbar, click Anything > Page Design > Sample Size Description.
- In the Complete data variable field (shown in the object inspector) select a variable (see requirements above). Whatever variable is selected will be used to compute the sample size, based on all responses without missing values.
- [Optional]: Select the filters applied to outputs on the page in the Filter(s) dropdown. This ensures the sample size shown will be adjusted for filtering.
- [Optional]: Select the weights applied to outputs on the page in the Weight dropdown. This ensures the sample size shown will be adjusted by the weight.
[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.
- Check Automatic, if not already ticked. This ensures that whenever the data changes, including when a viewer applies a filter in View Mode, the sample size description will update accordingly.
- [Optional]: Use the Properties > APPEARANCE menu to customize the background font color, font size, font style, border, etc as desired.
