Working with Date Fields: Discrete and Continuous Time Flashcards
Section 8
Which pane are dates shown in?
Dimensions
When you bring a date field into a view, which part of the date does Tableau display automatically?
The highest-level date part - usually year
Dates from what types of data sources cannot be modified in Tableau?
Cube or multi-dimensional data sources
What is the difference between using date parts and date values in a view?
Date parts aggregate based on that part alone, ignoring other parts – e.g. January includes ALL Januarys, not just January 2019. Date values are complete specific dates to a specific level of detail
What is the difference between discrete and continuous fields?
Continuous fields can have any value along an infinite line, and discrete fields fall into distinct categories
How are discrete and continuous fields displayed differently in a view in Tableau?
Continuous fields are green, discrete fields are blue
When you use a continuous field in a view Tableau creates…
An axis
When you use a discrete field in a view, Tableau creates…
Headers or categories
When should you use a continuous date field?
To visualize data over time
When should you use a discrete date field?
To visualize data across specific date parts
How do you change a field from discrete to continuous or vice versa?
Dropdown on the field
Does changing a date field between discrete and continuous also change it between a date part and a date value?
No
In the date dropdown, which is on top, continuous date values or discrete date parts?
Discrete date parts
Do dates default to discrete or continuous in Tableau?
Discrete
