What’s New in the Power BI April 2026 Update?

Latest Power BI April 2026 Updates

This blog breaks down the most practical updates from the Power BI April 2026 release – what changed, why it matters for real reporting workflows, and where the impact shows up fastest for teams managing analytics and Power BI services. It starts with Copilot on Mobile, then covers reporting and theming improvements, modeling enhancements, and a quick look at notable visualization updates.

Copilot on Mobile: Faster insights with conversational analytics

Until now, getting answers from your data meant waiting for an analyst. The Power BI April 2026 Update changes that. In-report Copilot in the Power BI mobile app has been upgraded, you can open a report on your phone or tablet, tap Copilot, and have a full, back-and-forth conversation with the data in front of them.

• Ask open-ended questions and follow up in context (not limited to summaries or prebuilt prompts).
• Understand what is driving a KPI or variance without switching apps or waiting on a team.
• Get answers with citations back to the exact visuals Copilot used, making insights easier to validate.
• Request AI-generated visualizations to take analysis further while staying grounded in the same report.
• The new voice dictation feature on iPhone and iPad makes it easy to capture questions hands-free and get answers quickly while traveling or reviewing results.
• For organisations where decisions span time zones and boardrooms, reducing insight lag by even an hour creates a compounding edge in the speed and quality of every decision made.

Reporting

1. Modern visual defaults and customized theme improvements (Preview)

This month’s update introduces a base theme switcher in the Customize current theme dialog (View ribbon > Themes). If your custom theme isn’t fully compatible with the new modern defaults yet, you can quickly switch back to the previous base theme while you update it. You can also use the same switcher to bring an older report up to date by moving it from its original base theme to the latest one.

Canvas settings now include common page sizes for each aspect ratio, with custom dimensions still available. Table and matrix styles have been corrected – banded rows are on by default, matrix +/- buttons are restored, and axis colors now use the right structural color (fixing Innovate and Orchid theme issues). Theme tiles also have a refreshed look, and Reset to default is now clearly marked. To update an existing report, select Update theme in Customize current theme or choose Reset to default from Themes.

2. Fixed size layout for card, button slicer, and list slicer visuals

Card, button slicer, and list slicer visuals now include a Fixed size option in Layout. Now, you can set exact pixel dimensions for each item instead of a fixed item count, and the scroll bars appear automatically when space runs out. Plus, Autogrid has also been renamed to Fit to space: on to resize items to fill the container and off to reserve space for the set item count (including the list slicer setting).

Fixed size lets you lock in precise item dimensions. Even as you resize the visual container, each card, button, or list entry keeps its set height and width instead of scaling. That makes it easier to maintain consistent layouts across a page – or match sizing across multiple visuals. In list slicers, it’s especially helpful for hierarchies: as levels expand or collapse, spacing stays steady and readable.

To use fixed size:

• Select the visual.
• In the Format pane, open Layout (under Multi-card layout or Multi-button layout), then switch Fixed size to On.
• Choose your arrangement and set dimensions in pixels:

1. Vertical: Height
2. Horizontal: Width
3. Grid: Height and Width

• Once Fixed size is on, Fit to space turns off automatically because you’re controlling dimensions explicitly.

3. Card visual: category interactivity and formatting updates

The card visual now makes your selection obvious. When you click a category header, the active card highlights while the rest fade. If you add multiple columns to the category field, their values are neatly combined in the header for a cleaner look. In addition, with Edit interactions, you can choose which visuals the card filters. Base64-encoded top-level images also render correctly, so you can use images from your data as-is.

4. Scatter charts: Autofit markers

Scatter charts now include an Autofit markers option that automatically expands the plot area so markers and bubbles near the edges stay fully in view. That means no more tweaking min/max axis ranges just to avoid clipped points.

5. Axis improvements for bar and column charts

The new Rounded range option trims away extra axis padding, so the value axis starts right where your data begins. Moreover, when you turn on data labels, the axis range stays put, so no more unexpected shifts.

6. Azure Maps visual: map style picker sync

When you change the map style using the in-visual style picker, the selected style now persists with the Format pane. Your styling choices stay consistent across both the style picker and the Format pane, giving you predictable behavior as you design your reports.

7. Preview visuals identified in Visualizations pane

Preview visuals in the Visualizations pane now display (preview) after their names for easy identification. They also appear below the divider in the pane, grouped with custom and unpinned visuals, clearly separated from generally available ones. These updates make it quicker to recognize when you’re working with a preview feature, addressing previous feedback about unclear preview status notifications.

8. Narrative visual default type update

The Narrative visual offers two modes: Copilot and Custom. This gives report authors real flexibility in how they craft summaries. The experience just got smarter, too. If you have a Copilot license, the visual now opens directly in Copilot mode, putting AI-powered insights front and center without any extra steps. The update also raises the character limit to 10,000, making room for richer, more detailed narratives. Switching between modes remains effortless, keeping you in full control of your storytelling workflow.

Modeling

1. Direct Lake calculated columns and tables (Preview)

Direct Lake storage mode delivers impressive performance straight from OneLake – so, no heavy refreshes, no unnecessary overhead. Power BI’s April 2026 update builds on this with two handy additions: unmaterialized calculated columns on Direct Lake OneLake tables (rolling out over the next few weeks) and calculated tables referencing Direct Lake OneLake columns. Both are a real win when adding columns or building tables upstream isn’t feasible – particularly when OneLake data preparation is owned by a different team.

2. User-context-aware calculated columns (Preview)

Power BI’s latest update lets calculated columns dynamically respond to DAX functions like UserCulture(), UserPrincipalName(), and CustomData(). With this, it is possible to unlock scenarios such as data translations tailored to individual users. Configurable via the Expression Context property, this works across Direct Lake on OneLake, Import, and DirectQuery tables. Direct Lake on OneLake support is rolling out over the next few weeks.

3. DAX user-defined functions: NAMEOF enhancements (Preview)

The DAX NAMEOF function just got a meaningful upgrade. As part of the ongoing DAX user-defined functions preview, you can now control exactly how object names are returned – a small change with a big impact on flexibility.

The updated function signature:

NAMEOF ( <object> [, <component> [, <escaped>]] )

Here’s what’s new:

• Choose your component – return just the table, column, measure, or calendar name, rather than the full reference.
• Control formatting – decide how that name is displayed, making it far more useful in display-facing scenarios.
• Backward compatible – existing models remain unaffected; current behavior is fully preserved.

It’s a practical enhancement for anyone building more dynamic, programmatic DAX logic – especially when clean, targeted name references matter.

Visualizations

1. Date Picker by Powerviz

The Powerviz Date Picker brings a polished, modern calendar experience to Power BI reports. Key highlights include:

• Smart Button Label – displays selected range or preset name instantly
• Custom Preset Title – localize preset names for your audience
• 15+ themes with full customization for brand consistency
• Pop-up & Canvas modes, holiday/weekend styling, and single or double-month views

2. Drill Down Waterfall PRO by ZoomCharts

The latest update to Drill Down Waterfall PRO makes financial and operational storytelling noticeably sharper. The standout addition is Automatic Change Thresholds – it detects subtotals automatically and calculates differences between consecutive segments, making multiperiod reports much easier to follow.

Other solid features include:

• Custom Sequence – full control over column ordering
• Drill Down – explore data directly on the chart
• Annotations – add markers and comments for context
• Cross-chart filtering – dynamic, interactive report experiences

A well-rounded visual worth adding to your toolkit.
