What are Measure Names and Measure Values in Tableau?

In Tableau, Measure Names and Measure Values are special, auto-generated fields that unlock powerful dynamic analysis capabilities. They are fundamental to understanding how Tableau handles multiple measures simultaneously, especially when you want to display, compare, or perform calculations across them without creating individual calculated fields for each one.

Imagine you have several quantitative fields you want to visualize side-by-side, like Sales, Profit, and Quantity. Instead of dragging each measure individually to the Rows or Columns shelf, you can leverage Measure Names and Measure Values. Measure Names acts as a dimension that lists the names of all the measures you’ve included in the view, while Measure Values acts as a measure that holds the corresponding numerical data for each measure name.

Who should use Measure Names and Measure Values?
Anyone working with Tableau who needs to:

• Display multiple measures in a single chart or table.
• Create dynamic comparisons between different metrics.
• Build dashboards with flexible measure selection.
• Perform calculations that reference different measures programmatically.

Common Misconceptions:

• Misconception: Measure Names/Values replace the need for creating new calculated fields. Reality: They *complement* calculated fields. You often create calculated fields *first*, and then use Measure Names/Values to display them dynamically.
• Misconception: You can’t filter or segment by individual measures. Reality: You can filter the *set* of measures shown using the Measure Names filter, but filtering based on a measure’s *value* within a dynamic setup requires more advanced techniques, often involving Level of Detail (LOD) expressions or specific calculated fields.
• Misconception: They are always automatically available. Reality: They appear when you drag multiple measures onto the view. You can also explicitly add them from the Data pane if needed.

Understanding Measure Names in Calculated Fields: Formula and Explanation

When you utilize Measure Names and Measure Values within a calculated field in Tableau, you’re essentially writing logic that can adapt based on which measure is currently being considered in the visualization’s context. This is particularly powerful when you want a single calculation to behave differently depending on the measure it’s applied to.

The core concept revolves around filtering the Measure Names field. A typical calculated field might look something like this:

IF [Measure Names] = "Sales" THEN [Measure Values] * 1.1 ELSEIF [Measure Names] = "Profit" THEN [Measure Values] * 0.9 ELSE [Measure Values] END

Step-by-Step Breakdown:

1. Context: Tableau places the measures you want to compare onto the view. This automatically generates the Measure Names (dimension) and Measure Values (measure) fields.
2. Measure Names Field: This dimension contains a distinct entry for each measure included in the view (e.g., “Sales”, “Profit”, “Quantity”).
3. Measure Values Field: This measure contains the numerical value corresponding to the Measure Name currently being processed in that row/mark of the visualization.
4. Calculated Field Logic: Inside a calculated field, you can use `IF` or `CASE` statements referencing `[Measure Names]` to conditionally apply logic or return specific values based on the measure’s name. The calculation often involves `[Measure Values]` to reference the actual data point.

Formula Explanation:
The general structure for using Measure Names in calculated fields involves conditional logic based on the `[Measure Names]` field.

CASE [Measure Names]
WHEN "MeasureA" THEN Calculation_for_MeasureA
WHEN "MeasureB" THEN Calculation_for_MeasureB
ELSE Default_Calculation
END

Where:

• [Measure Names]: The dimension field listing the names of the measures in the view.
• "MeasureA", "MeasureB": Specific names of measures you are targeting in your calculation. These must match the exact names of your measures.
• Calculation_for_MeasureA: A formula applied *only* when the current measure is “MeasureA”. This often uses `[Measure Values]`.
• Calculation_for_MeasureB: A formula applied *only* when the current measure is “MeasureB”.
• Default_Calculation: A fallback calculation applied to any other measures included in the view.

Variables Table

Variable	Meaning	Unit	Typical Range
[Measure Names]	The name of the measure being evaluated.	String	e.g., “Sales”, “Profit”, “Quantity”, “Custom Measure”
[Measure Values]	The numerical value of the measure being evaluated.	Numeric (e.g., Currency, Count)	Depends on the measure’s data (e.g., 0 to millions, negative values possible)
Specific Measure Field (e.g., `SUM([Sales])`)	The aggregated value of a specific measure.	Numeric	Depends on the measure’s data.
Conditional Calculation Result	The output of the calculated field.	Numeric / String (depends on calculation)	Varies based on the logic applied.

Practical Examples (Real-World Use Cases)

Let’s explore how using Measure Names in calculated fields can be applied in practical scenarios.

Example 1: Applying Different Commission Rates

Scenario: You want to calculate a commission based on sales performance, but the commission rate differs for different product categories or regions, which you are visualizing side-by-side using Measure Names. Let’s say you have “Total Sales” and “Target Sales” as measures. You want to apply a 10% commission on “Total Sales” but only if “Total Sales” exceeds “Target Sales”, otherwise, the commission is 5%.

Setup:

• Measure 1: Total Sales (Value: 50,000)
• Measure 2: Target Sales (Value: 45,000)

You drag both “Total Sales” and “Target Sales” to the Columns shelf. Tableau automatically creates [Measure Names] and [Measure Values].

Tableau Calculated Field:

CASE [Measure Names]
WHEN "Total Sales" THEN
    IF SUM([Measure Values]) > LOOKUP(SUM([Measure Values]), -1) THEN SUM([Measure Values]) * 0.10  // 10% commission if > Target Sales
    ELSE SUM([Measure Values]) * 0.05 // 5% commission otherwise
    END
ELSE 0 // No commission calculation for other measures like Target Sales itself
END
                    

*(Note: `LOOKUP(SUM([Measure Values]), -1)` is a Tableau Table Calculation used here to reference the previous measure’s value, assuming “Target Sales” comes before “Total Sales” in the view’s order. A more robust solution might involve LODs or specific field references if not using Measure Names dynamically).*

Calculator Simulation:
Let’s simplify for the calculator: Assume we have Measures “Sales” (Value: 50000) and “Target” (Value: 45000). We want a “Commission” output.

If [Measure Names] = “Sales”, apply commission:
IF [Measure Names] = "Sales" THEN IF [Measure Values] > 45000 THEN [Measure Values] * 0.10 ELSE [Measure Values] * 0.05 END ELSE 0 END

Inputs: Measure 1 Name: “Sales”, Measure 1 Value: 50000; Measure 2 Name: “Target”, Measure 2 Value: 45000.
Calculation Logic (simplified):
IF [Measure Names] = "Sales" THEN IF [Measure Values] > 45000 THEN [Measure Values] * 0.10 ELSE [Measure Values] * 0.05 END ELSE 0 END
Result: 5000 (Calculated Commission: 50000 * 0.10)

Interpretation: The calculated field correctly identified “Sales” and applied the 10% commission rate because the sales value (50,000) exceeded the target (45,000).

Example 2: Conditional Formatting Value Display

Scenario: You are displaying “Revenue” and “Cost” using Measure Names. You want to highlight revenue figures above a certain threshold but not cost figures.

Setup:

• Measure 1: Revenue (Value: 100,000)
• Measure 2: Cost (Value: 70,000)

Tableau Calculated Field (for display):

IF [Measure Names] = "Revenue" THEN
    IF SUM([Measure Values]) > 80000 THEN
        STR(SUM([Measure Values])) + " (High)"
    ELSE
        STR(SUM([Measure Values]))
    END
ELSE
    STR(SUM([Measure Values]))
END
                    

Calculator Simulation:
Inputs: Measure 1 Name: “Revenue”, Measure 1 Value: 100000; Measure 2 Name: “Cost”, Measure 2 Value: 70000.
Threshold: 80000.
Calculation Logic:
IF [Measure Names] = "Revenue" THEN IF [Measure Values] > 80000 THEN STR([Measure Values]) + " (High)" ELSE STR([Measure Values]) END ELSE STR([Measure Values]) END

Result: “100000 (High)” for Revenue, “70000” for Cost.

Interpretation: The calculated field checks if the measure is “Revenue”. If it is, it then checks if the value exceeds 80,000. If both are true, it appends ” (High)” to the string representation of the revenue. Otherwise, it displays the measure value as is. This allows dynamic conditional display logic based on the measure name. This technique is crucial for dynamic dashboards.

Key Factors Affecting Measure Names Calculations in Tableau

While the calculator simplifies the concept, real-world Tableau calculations involving Measure Names are influenced by several factors:

• Aggregation Level: The specific aggregation used (SUM, AVG, MIN, MAX) on your base measures significantly impacts the `[Measure Values]` field. Ensure your calculations align with the desired aggregation.
• Data Structure: The way your data is organized (e.g., wide vs. tall format) affects how measures are presented and how `[Measure Names]` / `[Measure Values]` behave.
• Filter Context: Filters applied to the worksheet, dashboard, or data source will alter the subset of data `[Measure Values]` represents, and consequently, your calculated field’s output. This is crucial for dynamic filtering.
• Table Calculation Dependencies: If your calculation relies on other table calculations (like LOOKUP, INDEX, RANK), their configuration (Compute Using, Restarting Every) becomes critical. The order of measures matters significantly when using relative table calculations.
• Measure Order: The order in which measures appear on the Marks card or shelf directly influences which measure `[Measure Values]` represents at any given row or mark, especially critical for table calculations referencing relative positions. This impacts calculations using `LOOKUP(…, -1)`.
• Field Types: Ensuring you are referencing measures correctly (as numerical values) and dimensions (like `[Measure Names]`) is vital. Mixing types incorrectly will lead to errors.
• Context Filters: Using context filters can change the order of operations, potentially affecting the results of calculations that depend on filter order or `[Measure Values]` evaluation.
• Data Blending/Joins: If your analysis involves multiple data sources, the structure resulting from joins or blends can influence how measures are aggregated and how `[Measure Names]` behaves, potentially requiring careful handling of `[Measure Values]`.

Frequently Asked Questions (FAQ)

Q1: Can I use Measure Names directly in a standard calculated field without putting measures on the view?

A1: No, the `[Measure Names]` and `[Measure Values]` fields are generated dynamically by Tableau when you place multiple measures onto shelves like Rows, Columns, or the Marks card. You need at least two measures in the view for these fields to appear and be usable in calculations.

Q2: How do I reference a *specific* measure’s value within a `[Measure Names]` calculation, not just `[Measure Values]`?

A2: You typically achieve this by combining `[Measure Names]` with a specific measure field using conditional logic. For example: IF [Measure Names] = "Sales" THEN SUM([Sales]) * 1.1 ELSE SUM([Profit]) END. However, if you simply need the value of the measure currently represented by `[Measure Names]`, you use `[Measure Values]`.

Q3: What happens if I use `[Measure Values]` in a calculation but don’t have multiple measures on the view?

A3: If only one measure is present, `[Measure Names]` will contain only that measure’s name, and `[Measure Values]` will hold that single measure’s aggregated value. Your calculation might still work, but it won’t demonstrate the dynamic comparison capability. If no measures are present, `[Measure Values]` will likely return NULL or zero.

Q4: Can I filter *which* measures appear in the `[Measure Names]` field?

A4: Yes. When you have `[Measure Names]` and `[Measure Values]` on your view (e.g., `[Measure Names]` on Color and `[Measure Values]` on Text), you can drag `[Measure Names]` to the Filters shelf. This allows you to select which specific measures you want to include or exclude from the view, thus controlling what `[Measure Names]` represents.

Q5: How does `[Measure Values]` relate to individual measure aggregations like `SUM([Sales])`?

A5: When multiple measures are involved, `[Measure Values]` dynamically takes on the aggregated value of the specific measure indicated by `[Measure Names]` for that particular row or mark in the visualization. For a single measure, `[Measure Values]` often reflects the primary aggregation (e.g., `SUM([Sales])`) if “Sales” is the only measure in context.

Q6: Can I use `[Measure Names]` in Level of Detail (LOD) expressions?

A6: Generally, no. `[Measure Names]` and `[Measure Values]` are generated fields tied to the visualization’s context. LOD expressions operate at different data granularity levels and typically cannot directly reference these dynamic fields. You would usually need to achieve similar results by referencing specific measures within the LOD or using table calculations outside the LOD.

Q7: What’s the difference between using `[Measure Names]` in a calculated field versus using it on the Color shelf?

A7: Using `[Measure Names]` on the Color shelf assigns a different color to each measure’s data points, visually distinguishing them. Using it within a calculated field allows you to apply conditional *logic* based on which measure is currently being processed. You can often combine both: use `[Measure Names]` on Color for visual distinction and in a calculation for conditional analysis.

Q8: How do I handle calculations where the *order* of measures matters, like differences?

A8: This is where it gets tricky. `[Measure Values]` doesn’t inherently know the order you placed measures. For ordered calculations (like `[Sales] – [Previous Month Sales]`), you typically need to use Tableau’s Table Calculations (e.g., `LOOKUP`, `ZN`) and configure their “Compute Using” setting carefully, often based on the `[Measure Names]` dimension or a discrete date field. The calculator simulation simplifies this aspect. Explore advanced Tableau table calculations for these scenarios.
