Dax Function: RANGE
Category: Filter Functions
The RANGE function in Power BI is used to create or analyze a range of numeric values or identify the minimum and maximum range of data within a dataset or specified group. It is commonly used in numerical computations, trend analysis, and range-based filtering.
Purpose
Boundary Identification: Helps identify the upper and lower bounds in a dataset.
Data Filtering: Filters datasets based on a specified numerical range.
Calculation Scope: Defines limits for calculations or aggregations.
Type of Calculations
Range Calculation: Determines the difference between the maximum and minimum values.
Filtering: Extracts data within a specified range of values.
Dynamic Scaling: Adapts calculations dynamically based on input ranges.
Practical Use Cases
Sales Threshold Analysis: Find transactions within specific sales ranges.
Outlier Detection: Highlight data points that lie outside a specified range.
Trend Smoothing: Apply calculations to subsets of data within a moving range.
RANGE(<start>, <end>)</end></start>
| Parameter | Type | Description |
|---|---|---|
Start | Scalar | The starting value of the range. |
End | Scalar | The ending value of the range. |
How Does RANGE Dax Works
Range Specification: Define the starting and ending bounds of a range.
Value Evaluation: Evaluate whether values within a dataset fall inside the specified range.
Dynamic Adjustment: Use in conjunction with other DAX expressions to dynamically compute metrics within the range.
Formula Example:
Filter sales data between 100 and 500:
FilteredSales = FILTER(Sales, RANGE(100, 500))What Does It Return?
Table or Scalar: Depending on usage, the function returns either a set of values within the range or a computed scalar value representing the range.
When Should We Use It?
To calculate the spread of data points (e.g., min-max difference).
For conditional calculations or filtering data by numeric ranges.
To dynamically adjust metrics in dashboards based on user inputs.
Examples
Basic Usage :
Calculate the range of values in a column:
ValueRange = MAX(Sales[Amount]) - MIN(Sales[Amount])
Column Usage
Filter data for values between 50 and 100:
FilteredTable = FILTER(Sales, RANGE(50, 100))
Advanced Usage
Combine with aggregation functions to analyze trends:
RangeSum = SUMX(FILTER(Sales, RANGE(100, 500)), Sales[Amount])
Tips and Tricks
Boundary Inclusivity: Ensure you understand whether the range is inclusive or exclusive based on your dataset needs.
Combine with Aggregations: Use in conjunction with SUMX, AVERAGEX, etc., for meaningful insights.
Dynamic Ranges: Leverage slicers or parameters to create interactive ranges for users.
Performance Impact of RANGE DAX Function:
Dataset Size: Ensure that the range parameters are optimized for large datasets to avoid performance bottlenecks.
Pre-Filter Data: Filtering data before applying the RANGE function can enhance performance.

It specifies a numeric range and evaluates whether data points fall within this range.
No, the RANGE function is specifically designed for numeric data.
Typically, the function includes the start and end boundaries, but this depends on the context of use.
RANGE specifies numeric boundaries, while FILTER is a general-purpose function for filtering data based on conditions.
Yes, you can pair RANGE with slicers or parameters for dynamic range selection.
