In this tutorial, an expert from Pragmatic Works breaks down the essential features of Power BI slicers, demonstrating how to use both the traditional and new slicer visuals to filter and enhance reports effectively.
What Are Power BI Slicers?
Slicers are on-page filtering tools in Power BI that allow end-users to filter data interactively within a report. They provide a user-friendly way to "slice and dice" data for better insights.
Types of Slicers Available in Power BI
Power BI offers two slicer visuals:
- Traditional Slicer: Standard dropdown and list view slicer.
- New Slicer (Button Style): A visually enhanced slicer with button-based interaction and more design flexibility.
How to Use the Traditional Slicer
The traditional slicer works as an on-page filter. Here's how to use it:
- Drag the slicer visual onto your report page.
- Assign a data column (e.g., Year) to the slicer.
- Select a value from the slicer to filter the visuals on the page.
- Multiple slicers can be added for layered filtering.
Styling Options for the Traditional Slicer
The traditional slicer offers several layout styles accessible through the Format Pane:
- Vertical List: Displays all items vertically.
- Dropdown: Saves space with a collapsible dropdown list.
- Tile: Turns slicer options into clickable buttons.
Advanced Date Filters
When working with date fields, Power BI offers additional slicer styles:
- Between: Adjustable slider for start and end date filtering.
- Less Than or Equal To: Filters up to a set date.
- Greater Than or Equal To: Filters from a specific date onward.
Exploring the New Button Slicer
The new slicer, identified by a lightning bolt icon, introduces a more modern and interactive way to filter data:
- Button-based interaction for faster selection.
- Background images and icons for enhanced visual appeal.
- Supports both single and multi-select options.
- Option to enable a "Select All" button for easy bulk selection.
How to Customize the New Slicer
To style the new slicer for better user experience:
- Open the Format Pane.
- Enable Background Images or Icons for a visually rich slicer.
- Adjust the size, font, and button styles to fit your report theme.
- Enable the Select All option for bulk filtering.
Best Practices for Using Slicers
- Use button slicers for simpler and more intuitive filtering.
- Minimize slicer clutter by grouping similar fields together.
- Ensure date slicers match the data granularity for clarity.
- Test the slicer behavior to match user expectations.
Conclusion
Power BI slicers are essential tools for dynamic data filtering and report enhancement. Whether using the traditional or new slicer style, they empower users to control how they view data insights effectively.
