Report all events with non-standard size (or empty)

Question

I have a custom size for a custom range and want to know if this dimension applies to all the required events.

I created my own report with the "Event" - "Event Value" fields and tried to filter it in the "Custom Dimension" field. The problem is that there are no such events - no events with an empty "user dimension" value.

Is there a need to explicitly set a filter for a custom dimension (for example, for an empty string) or are there no events with an empty "custom dimension" value?

Custom dimensions, such as event sizes, do not have (not specified) or an empty value that can be requested. Only events with non-empty values ​​will be displayed in the report. To get the rest, you need to get all the totals and subtract.

Answer 2

It may be an anti-pattern, but technically you can get around this limitation by setting your dimensions to the default value.

{{MyCustomDimension}}-foo 

If your empty dimensions will display as -foo and forward.

If a dimension has been provided, you expect to see it in analytics as the dimension value, followed by -foo .

Take click events in google tag manager, for example:

 {{Click Element}}.{{Click Classes}} 

In the above example, we can always expect the click element to be defined, but not an attribute of the element class.
