Final answer:
Drag a discrete dimension to a worksheet in data visualization software to create categories. Label each column or axis with 'Quantity/units' for clarity. Discrete dimensions create segmented visual representations like tables or graphs.
Step-by-step explanation:
When a discrete dimension is dragged onto the worksheet, this would create a category (finite list). In data visualization software, specifically in the context of using tools like Tableau, dimensions represent qualitative values like categories or groupings. Dragging a discrete dimension, which could be a field like 'Country' or 'Product Category', onto a worksheet will allow the software to create different segments or headers in a visual representation, such as a table or a graph.
To accurately reflect the data, each column in a table or axis in a graph should be labeled to show both the quantity and the units, such as 'Revenue/USD'. This ensures that the numbers represented on the axis or within the table are understood to be measured against those units, indicating a pure number that can be analyzed to yield insights.
