Power BI Tooltips: From Beginner to Pro

Key insights

• Power BI tooltips: Small hover popups that show extra context for a data point, like values, KPIs, or short explanations.
  They give users instant detail without crowding the visual.
• Modern tooltip experience (2026 update): Lets authors enable interactive hover actions such as drill actions directly from the tooltip and choose clearer display modes without complex formulas.
  This reduces clicks and speeds insight discovery.
• Tooltip types: Know when to use each option—Default visual tooltip (auto-shows visual fields), Tooltip field well (add extra fields), Fields-only (show only chosen fields), Sentence format (present readable text), and Report page tooltip (use a full report page as a tooltip).
  Pick the type that matches your audience and detail needs.
• How to create report page tooltips: Build a new page, enable Allow use as tooltip in page settings, add visuals, then assign that page in the visual’s Tooltip > Page dropdown.
  This creates rich hover content with KPIs, charts, and explanations.
• Practical workflow: Start with the built-in tooltip, add fields when you need more context, switch to sentence format or fields-only for cleaner text, and use report page tooltips for complex detail or branding.
  Follow this progression to scale from beginner to expert.
• Why tooltips matter: They improve report clarity, reduce the need for extra drill pages, and let authors tailor wording and filters for business users.
  Modern tooltips boost on-hover exploration and help users act on insights faster.

Video overview and context

Fernan Espejo (Solutions Abroad) published a YouTube tutorial titled Power BI Tooltips (2026) - From Beginner to Expert, which walks viewers through the evolving tooltip capabilities in Microsoft Power BI. The video is structured with clear timestamps that mark the progression from default behavior to advanced custom pages, making it accessible for both newcomers and experienced report authors. Moreover, Espejo emphasizes practical examples so viewers can see each tooltip type in action and understand when to choose one approach over another.

The presentation highlights that, by 2026, tooltips have become more flexible and interactive, enabling drill actions directly from a hover state and reducing the need for extra clicks. Espejo frames the discussion around four main categories: default visuals, sentence-style formats, enriched tooltip fields, and full report page tooltips. Consequently, the video serves as both a tutorial and a decision guide for designers aiming to balance simplicity and control in their reports.

Tooltip types explained

Espejo outlines several tooltip options and explains their intended audiences, starting with the default visual tooltip for beginners that leverages fields already in the visual. Next, he shows how the tooltip field well lets authors add contextual fields without changing the visual layout, which is useful for intermediate users who need more detail without complexity. He then introduces the newer options like Tooltip fields only and Sentence format only, which let authors present concise, curated hover information without building custom calculations.

For advanced scenarios, Espejo demonstrates the report page tooltip, a fully designed page that appears as a hover card and can include charts, KPIs, and explanatory text. This approach gives maximal control over layout and content, and it supports interactive elements such as drill down and filtering behavior. However, he also notes that this power comes with additional design and maintenance responsibilities.

How to set up and use tooltips in practice

Espejo walks through the practical steps for each tooltip type, describing how to drag fields into the Tooltip field well for standard hover details and how to enable a page as a tooltip by setting Allow use as tooltip in the page information. He explains that a tooltip page must contain visuals and be explicitly assigned from the visual’s tooltip settings, which keeps the process transparent and repeatable. As a result, authors who follow these steps can quickly test different tooltip experiences across their reports.

Additionally, the video covers sentence templates that let authors reference tooltip fields directly in readable text, avoiding heavy DAX formulas. Espejo demonstrates hiding sensitive fields so users only see what’s relevant, which helps maintain clarity and security. In this way, the tutorial balances the mechanics of setup with tips to keep hover content meaningful and safe for viewers.

Tradeoffs and practical challenges

Espejo weighs the tradeoffs between simplicity and control, noting that default tooltips are low-effort but limited, while report page tooltips deliver rich context at the cost of design time and potential performance impacts. For example, heavy visuals or many calculations on a tooltip page can slow rendering, particularly on older devices or complex datasets. Therefore, authors must choose the right level of interactivity for their audience and environment.

He also discusses the challenge of maintaining consistency: using many custom tooltip pages can improve clarity for specific visuals but increases ongoing maintenance and testing work. Moreover, mobile users and assistive technologies may experience tooltips differently, so authors should verify usability across devices and consider fallback text where necessary. Ultimately, the decision often requires balancing user needs, report performance, and development overhead.

Recommendations and learning path

For learners, Espejo recommends a progressive approach: start with default visual tooltips, add fields as needed, then experiment with sentence-format or fields-only modes before moving to full report page tooltips. This staged path minimizes complexity early on while giving authors room to adopt richer experiences as their skills grow. Furthermore, practicing with small, focused tooltip pages helps authors learn how interactivity, filtering, and performance interact.

In closing, the video offers a pragmatic guide for anyone improving report clarity without overcomplicating their build process. By explaining when to use each tooltip type and describing the common pitfalls, Espejo helps viewers make informed choices that balance readability, control, and maintenance. Consequently, the tutorial is a useful resource for teams that want to elevate their Power BI reports with thoughtful, purposeful hover experiences.
