Power BI Enhancements You Need to Know – Part 7: Visual Calculations in Power BI

 

What Are Visual Calculations?

Visual calculations allow you to write DAX expressions directly within a visual—not in the model. Think of them as visual-specific calculations that make it easier to implement common business logic like running totals, moving averages, and custom comparisons without creating new measures or columns.

Example:

Key highlights:

  • Simpler DAX, better performance
  • Works only with data present in the visual
  • Calculated at the visual level, not in the model
  • Ideal for ad-hoc analysis and quick prototyping

How to Enable and Use Visual Calculations

Step 1: Enable the Feature (if needed)

  • Before September 2024: Go to Options > Preview Features > Enable Visual Calculations, then restart Power BI.
  • After September 2024: Enabled by default (still in preview).

 

Step 2: Add a Visual Calculation

  • Select a visual (e.g., table, matrix, chart).
  • Click on “New visual calculation” in the Home ribbon.

  • Use the formula bar to define your logic.

    Tip: No need to write SUM or CALCULATE unless aggregation is needed. Visual calculations behave like row-wise evaluations, similar to calculated columns.

Key Benefits of Visual Calculations

BenefitDescription
Simplified DAXWrite quick logic without complex syntax.
Performance GainsOperate on aggregated data rather than detail-level.
No Model ClutterDoesn't add temporary measures to your semantic model.
Ad-hoc FriendlyPerfect for analysis that doesn't need to persist.
Visual Context AwarenessAutomatically respects the structure and filters of the visual.

 

Templates & Quick Calculations

Templates are accessible via the drop-down under the New visual calculation button.

 

Limitations to Keep in Mind

Since visual calculations are still in preview, they come with a few restrictions:

 

Not supported on:

  • Slicers, R/Python visuals, Key Influencer, Q&A, Decomposition Tree
  • Metrics, Paginated Reports, Power Apps, Power Automate
  • Cannot be reused or copied across visuals
  • Not exportable in "underlying data" exports
  • Not supported in Power BI Embedded or Publish to Web
  • No personalization, sort order, or dynamic format strings
  • Self-referencing calculations not allowed

Final Thoughts

Visual Calculations in Power BI are a game-changer for analysts who want to create dynamic insights quickly without diving deep into complex DAX or expanding their data model unnecessarily.

 

They are simple, performant, and perfect for storytelling, especially during exploratory analysis or prototyping dashboards.

Import Microsoft Planner Data into Power BI Using Power Automate and SharePoint

Image
  In this guide, we’ll cover how to bring task data from Microsoft Planner into Power BI for analysis, using Power Automate and SharePoint as intermediaries. Since Power BI currently lacks a direct Planner connector, Power Automate lets us fetch the data from Planner and save it to SharePoint as a JSON file, enabling Power BI to access it on a scheduled basis. Prerequisites Before you begin, ensure you have: Access to Microsoft Planner  – to view and retrieve Planner task data. Power Automate License  – access to create and run Power Automate flows. SharePoint Access  – a SharePoint site to store JSON files. Using SharePoint simplifies the setup, as it doesn’t require a premium Power BI or Power Automate license. Power BI Desktop  – to set up and configure the JSON data connection and publish the report. Microsoft 365 Account  – for authentication, as we’ll be connecting Power BI to SharePoint through your organization’s Microsoft 365 credentials. Step 1: S...

Append vs. Merge in Power BI: Key Differences and Use Cases Introduction When working with data in Power BI, combining datasets is often essential for creating comprehensive reports. Power BI offers two primary methods for combining tables: Append and Merge . While both are used to consolidate data from multiple sources, they work in different ways and are suited for different scenarios. In this blog, we will explore the key differences between Append and Merge in Power BI, along with practical examples to help you choose the right approach for your data needs. 1. What is Append in Power BI? Append in Power BI is used to combine rows from two or more tables into a single table. The structure of the tables being appended should be similar (i.e., they should have the same columns), as Append simply stacks the rows on top of each other. Key Features of Append: Row Combination : Append combines rows from multiple tables, one after the other. No Column Matching : Columns are not matched b...
