Tableau-Desktop-Found Exploring and Analyzing Data Practice Question
When you drag a continuous date field (e.g., Order Date) to the Columns shelf, what does Tableau display by default?
⚠ Common exam trap
Candidates often confuse continuous green date fields with discrete blue date fields. They may expect a discrete header-based layout instead of the default continuous axis generated by green fields.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
A continuous time axis
Tableau defaults to showing a continuous time axis when a continuous date field is placed on the shelf. This allows for a smooth line chart that accurately reflects the temporal nature of the data. Understanding default behaviors helps analysts save time by avoiding unnecessary manual configuration of time scales, ensuring quick insights into trends, seasonality, and overall performance patterns over time.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
A list of discrete years
Why it's wrong here
Discrete years are shown when using a discrete date field (indicated by a blue pill). A continuous date field (indicated by a green pill) creates an axis rather than discrete headers. Displaying discrete years would break the continuous nature of the time axis required for accurate trend analysis.
- ✓
A continuous time axis
Why this is correct
When a continuous date field (green pill) is added to the Columns shelf, Tableau creates a continuous axis. This axis represents time as an unbroken sequence, allowing for the visualization of trends across dates and times in a way that respects the mathematical order of the data.
- ✗
A bar chart of frequencies
Why it's wrong here
Tableau does not automatically generate a frequency bar chart unless the user explicitly defines the 'Number of Records' or count measure. The default behavior for a continuous date is to create an axis for a line or area chart, not to switch the mark type to bars.
- ✗
A filter dialog box
Why it's wrong here
Dragging a field to the Columns shelf is a structural operation that defines the view layout, not an action that triggers a filter dialog. A filter dialog only appears if you drag the field directly onto the Filters shelf or use the right-click drag method to choose filter options.
