Different Types of Filters in Power BI 

Power BI offers various Filters for different data scenarios and analysis needs. These include basic, advanced time intelligence and top N Filters. Here's a comprehensive list:

Basic Filters  

Basic Filters are the foundation of the BI Filtering feature and include categorical and numerical options. They can be classified into two sub-categories: 

a) Categorical Filter: A categorical Filter allows you to include or exclude specific categories or values in your data. For example, you can choose a sales dataset to display data only for a particular product category, such as "electronics" or "clothing". This option helps you focus on specific subsets of data based on categorical attributes. 

b) Numerical Filter: A numerical Filter lets you select data based on numeric ranges or conditions. For instance, you can clarify an inventory dataset to show only products with prices greater than £50 or choose customer data to display those with ages between 25 and 40. It provides flexibility in analysing data based on numerical attributes.

Advanced Filters 

Advanced Filters provide more advanced capabilities for filtering data within specific visuals, pages, or even the entire report. It offers flexibility and customisation options beyond basic categorical and numerical Power BI Filters.  

a) Visual-level filter: A Visual-level option allows you to apply filters to specific visuals within a report. For example, suppose you have a bar chart representing sales by region. In that case, you can apply this option to display data only for a particular region, such as "North America". This option helps you focus on specific data within a particular visualisation. 

b) Page-level Filter: A Page-level option applies at the page level, impacting all visuals on a specific page. For instance, you can apply a Page-level Filter to show data for a specific time, such as "Q2 2022". This option helps you ensure consistency in data displayed across multiple visuals on a single page. 

c) Report-level Filter: A Report-level option applies Filters consistently across all pages and visuals within a report. It allows you to separate data at a broader scope, such as filtering to display data for a specific product line, like "Electronics". This option ensures uniformity and coherence in Data Analysis throughout the entire report. 

Time Intelligence Filters 

Time intelligence filters are specifically designed to analyse time-based data. These Power BI Filters provide functions and calculations that enable you to compare data across different time periods, such as year-to-date, quarter-to-date, or rolling averages. It helps you uncover trends, patterns, and seasonality in your data.  

a) Year-to Date Filter: A year-to-date option enables you to analyse data specifically for the current year, disregarding data from previous years. This option is particularly useful for tracking performance or comparing year-over-year metrics within a given time frame. 

b) Rolling Average Filter: A rolling average option allows you to calculate and visualise the average of a measure over a rolling time window. For example, you can apply a 7-day Rolling Average Filter to smooth out fluctuations and analyse trends in daily sales data. 

Top N Filters 

a) Top N Filter: A Top N Filter allows you to focus on the top values within a specific measure. For instance, you can apply a Top 10 filter to display the Top 10 highest-selling products based on sales revenue. This option helps identify the dataset's most significant or influential data points. 

b) Bottom N Filter: A Bottom N Filter is the counterpart of the top N option. It allows you to focus on the bottom values within a measure. For example, you can apply a Bottom 5 Filter to identify the five products with the lowest sales volume. This option helps identify outliers or underperforming data points. 

5) Relative Data Filters

Relative Data Filters are time-series Data Filters that allow you to Filter data for past ‘N’ days, weeks even months. It is one of the most effective Data Filters.

6) Slicer 

Slicer may not be considered a traditional Filter; however, its canvas visuals allow you to Filter page visuals. The interactive design offers a report with greater control over the data.

What is Cross filtering?

This Power BI function eliminates all data and saves the ones you wish to concentrate on. Stated differently, this functionality redraws the chart according to the selected filter. The cross filtering in Power BI empowers informed decision-making and actionable insights across various levels of analysis. It refines data at different levels-

a) Visual

b) Page

c) Report

Modes of Filters: Basic and Advanced

There are two filtering modes in Power BI. Let’s explore them in detail:

a) Basic Filtering: It offers you an expandable and searchable list. To find a value, all you need to do is type a word or identifier into the search field. In exchange, the search terms you typed cause an instantaneous update of the list of accessible values.

b) Advanced Filtering: This mode lets you choose more precisely what you wish to filter out. Advanced filtering options also differ depending on the type of columns used.

Power BI Slicer vs Filter

While Slicer and Filter share minimal similarities in terms of data segmentation and filtering, there are significant variations between them. Let’s explore those differences in detail:

Comparison of Filter Types

Filters are a fundamental component of visualisation tools like Power BI, enabling users to refine and focus on specific subsets of data. Let's delve into a comprehensive comparison of these filter types to understand their functionalities and advantages:

a) Automatic Filters: When you construct a visual, automatic filters are applied to the filter pane's visual level automatically. The fields that comprise your visual are the basis for these filters. With editing permissions to the report, users can edit, clear, hide, lock, rename, and sort this filter in the pane.

b) Manual Filters: When editing a report, you can drag and drop the manual filters into any area of the filter pane. These filters in the pane can be edited, deleted, cleared, hidden, locked, renamed, or sorted.

c) More Advanced Filters: Though less frequent, you should be aware of these filter kinds if your report includes them. While designing the perfect filter for your report, you might find them helpful.

d) Include and Exclude Filters: When you utilise a visual's include or exclude feature, the corresponding filters are automatically added to the filter pane. This filter in the pane can be sorted, locked, deleted, or hidden if you can alter reports. Also, such filters cannot be edited, cleared, or renamed.

e) Drill-down Filters: Drill-down filters are added to the filter pane automatically while using it for a report. You can modify or remove the filter in the pane if you are able to edit a report. This filter is linked to the drill-down features of visuals; thus, you cannot delete, hide, lock, rename, or sort it. 

f) Cross-drill Filters: Cross-drill filters are automatically added to the pane when a drill-down filter from the report page is applied to another visual using a cross-filter. This filter is linked to the drill-down functionality. Even though you can edit a report, you cannot remove, clear, hide, lock, rename, or sort it.

g) Drillthrough Filters: This feature can pass drillthrough filters from one page to another since the Drillthrough pane displays them. Drillthrough filters come in two varieties and are activated by the first type. This kind of filter can be edited, deleted, cleared, and hidden, just like any other report. Depending on the source page's page-level filters, the second kind is sent to the destination. Although this temporary drillthrough filter can be edited, deleted, and cleared, it cannot be hidden or locked for end users.

h) URL Filters: By adding a Uniform Resource Locator (URL) query parameter, URL filters are added to the pane. The filter in the pane can be edited, deleted, or cleared if you are able to edit a report. Because this filter is linked to the URL parameter, you are unable to hide, lock, rename, or sort it. 

i) Pass-through Filters: Visual filters produced by Q&A are called pass-through filters. While editing reports, you can delete, hide, or sort these filters in the pane. But these filters cannot be locked, cleared, edited, or renamed.

Conclusion 

In conclusion, Power BI Filters play a crucial role in Data Analysis and Visualisation by allowing you to refine your data views and focus on specific subsets of information. By understanding and effectively applying these Filters, you can uncover valuable insights, identify trends, compare data across different time periods, and highlight significant data points, enhancing the effectiveness of your Data Analysis endeavours.
