OK, now that we’ve gone over how to set up slicer values, let’s discuss how you can set up default slicer values in the next section.

Setting Default Slicer Values

In this section, we’ll delve into the concept of setting default slicer values in Power BI. It’s often necessary to establish a default setting that guides the user experience and ensures consistency in data analysis.

This process, while straightforward, can significantly enhance the efficiency and effectiveness of your Power BI reports. By setting default slicer values, you can control the initial view of your data, making it easier for your audience to understand the insights you’re presenting.

Let’s explore how to accomplish this task.

1. Using Measures

You can set the default slicer value by using measures. First, create a measure that captures your default selection criteria. Follow the steps below to set default values for your slicer.

1. In your Power BI report page, navigate to the Home tab and select New Measure.

When a user opens the report, the slicer will automatically display the default value of the month column that you’ve set using the measure formula and transform the report based on the default value selection.

2. Implementing SQL

Another approach to setting default slicer values is using SQL. With this method, you can write a SQL query to define the default value, which can be based on a specific condition or the latest available data. Follow these steps:

1. Connect to your SQL database in Power BI by clicking Get Data and selecting Import data from SQL Server.

SELECT MIN(Month) AS DefaultValue FROM Date

5. This logic fetches the earliest month in the dataset as the default value.

6. Load the query result into Power BI as a table. Add a slicer to the report and select or drag and drop the required data field into your slicer.

7. In the slicer settings, under the Selection pane, set the Single selection mode (Off).

8. Drag the new query table onto the Add data fields here box, under the filters panel of your Power BI Report, and set the default slicer value.

With these steps, you’ll have successfully implemented a default slicer value using SQL in your Power BI report!

Next up, let’s go over some advanced techniques using default slicer values.

Advanced Techniques for Default Slicer Values

In your quest to optimize Power BI reports, it’s essential to set up default slicer values that guide users toward the most relevant data.

In this section, we’ll discuss a few advanced methods — using SWITCH, SELECTEDVALUE, numeric range slicer, and OFFSET to establish more dynamic and flexible default values.

1. SWITCH Function

The SWITCH function allows you to match a single expression against multiple values. To use SWITCH in your slicer, create a measure that returns the default value based on the user’s selection.

It’s particularly useful when you want to set default values for categorical slicers based on specific conditions.

For example, consider a sales report with a region slicer. You can use SWITCH to set the default value to be the region with the highest sales.

Selected Region = 
VAR max_sales = MAXX('Sales', 'Sales'[Region Sales])
        SELECTEDVALUE('Sales'[Region], "All") = max_sales, "Highest Sales",


This function retrieves a single value from a slicer. It returns the selected value if there’s only one, or a specified alternate result if multiple values are selected. You can use SELECTEDVALUE in conjunction with other functions to create measures that adapt dynamically to user selections.

A common use case for SELECTEDVALUE is to set a default time period, such as displaying data for the current month or year. This approach can make your reports more intuitive and relevant to users.

Suppose you have a sales report with a revenue range slicer. To set an average revenue range as the default value, use the following code:

Average Sales Bins = 
VAR Average_Revenue = AVERAGEX('Sales', 'Sales'[Revenue])
        SELECTEDVALUE ('Sales'[Revenue]) = Average_Revenue,
        "Average Revenue",
        SELECTEDVALUE ('Sales'[Revenue], "All")

3. OFFSET Function

The OFFSET function lets you create a measure that sets a default value based on a relative position. It’s helpful when you want to generate rolling windows or moving averages. To implement OFFSET, you’ll need to employ time intelligence functions and create measures that compute relative periods.

For example, you can set the default date slicer to the past three months using OFFSET as follows:

Default Date Range = 
VAR Past_3_Months = TODAY() - OFFSET(DateTable[Dates], -3, MONTH)
        SELECTEDVALUE(DateTable[Dates], Past_3_Months)

By leveraging these advanced techniques, you can create efficient and user-friendly default slicer values in your Power BI reports.

Comparing Values with Slicers

Power BI slicers enable you to easily compare values, ratios, and profits in your data. By leveraging slicers, you can filter your data to analyze specific segments, providing you with a clear and concise view of the information you need.

To start comparing values using a slicer, follow these steps:

  1. Add a slicer to your report canvas by going to the Visualizations pane and selecting the Slicer icon.
  2. Drag the desired field from the Fields pane to the newly created slicer. This will allow you to filter your data by that field.

Consider this example: Compare the % units market share for different manufacturers by segment. Drag the Manufacturer and Segment fields into the slicer. You can then select specific segments for each manufacturer from the slicer to view their % Units Market Share.

Compare Values using Slicer in Power BI

To get an even clearer comparison, add visuals such as bar or pie charts to your report canvas. These visuals allow you to see patterns and trends at a glance, making it easier to understand the data as shown above.

When using Power BI slicers to compare values, keep the following best practices in mind:

  • Use the Multi-select option: This feature allows you to select multiple values within a slicer, making it easier to compare different data points.
  • Apply consistent formatting: To make your slicers visually appealing and easy to read, apply a consistent format to all slicers in your reports.
  • Keep the data up to date: Ensure that your data source is always updated to get accurate comparisons and insights from your slicers.

By following these guidelines, you will be able to confidently and effectively compare values, ratios, and profits with Power BI slicers in a clear and knowledgeable manner.

Final Thoughts

With Power BI, you can easily implement a default slicer value in your reports. This solution not only helps tailor your data visualization but also provides a better user experience by focusing on the most relevant information.
