In 2025, Power BI continues to solidify its position as a leading business intelligence tool, with over 97% of Fortune 500 companies utilizing its dashboards to make informed decisions. This widespread adoption underscores Microsoft’s commitment to enhancing data analytics capabilities across industries.
A key factor in Power BI’s success is its regular monthly updates, introducing features that refine data visualization and user interaction. The October 2024 update is no exception, bringing significant improvements to marker customization in line, scatter, and anomaly charts.
These enhancements provide users with greater control over marker attributes, including shape, size, rotation, color, transparency, and borders. Such flexibility allows for more precise data representation, aiding in clearer trend analysis and storytelling.
In this blog, we’ll delve into the specifics of these marker enhancements, providing a comprehensive guide on how to leverage these new features to elevate your Power BI reports.
What Are Marker Enhancements in Power BI? Marker Enhancements in Power BI refer to the new customization options added to markers—those small shapes or points that show up on the line charts, scatter plots, and anomaly visuals. These markers help users spot key data points, trends, or changes across a timeline or category.
Before October 2024, marker styling was basic. You could only switch them on or off and had very limited control over how they looked. With the latest update, Microsoft has opened a full panel of styling options that let you tweak markers in more detail.

8 Key Features of Marker Enhancements in Power BI This feature added several new options that give you more control over how markers look and behave in your visuals. Here’s a rundown of the most important features:
1. Per-Category and Per-Series Customization You can now customize markers based on either:
Category level – Useful when your chart doesn’t have a legend. Each x-axis value (like months or product names) can have its own marker style. Series level – When your chart includes a legend, each data series can be styled separately. This flexibility means you can style data points exactly how you need them, depending on how your chart is structured.
2. More Shape Options You’re no longer stuck with default circles. Now you can choose from multiple shapes such as:
And more. This helps in clearly distinguishing between different data series or categories.
3. Rotation Support Except for the circle, all shapes now support rotation. For example, a triangle rotated 90 degrees can point up or down depending on the message you want to convey. This is useful when overlapping lines make markers hard to distinguish.
4. Customizable Size You can adjust the marker size globally or for individual series or categories. This makes it easy to highlight specific data points or reduce clutter in busy charts.
5. Color and Transparency Controls Markers can now be styled with:
Adjustable transparency, from fully visible to completely invisible You can use transparency to tone down less important data points or hide markers altogether without deleting them.
6. Marker Borders This is a new addition. You can now add borders to markers and control:
Borders help make markers stand out, especially when using similar colors across series.
7. Line Visibility Control You can now reduce a line’s thickness to zero, effectively hiding the line and showing only the markers. This is useful when you only want to show individual data points without any connecting lines.
8. Settings Persistence If you apply marker settings before adding more series, Power BI retains those changes. This is handy when you want to lock in a design before expanding your visual.
Steps to Enable Marker Enhancements in Power BI Before customizing markers, you need to know where the options live in Power BI’s interface.
Here’s a quick walkthrough to help you get started.
1. Add a Visual to Work With Start by adding a visual where markers apply — such as a line chart, scatter plot, or anomaly detection visual.
Example: Power BI Desktop.
2. Open the Format Pane This is where you’ll access all customization settings.
If the Format pane isn’t showing: Go to the top ribbon and click on “View”. Check the box next to “Format Pane” to enable it.
3. Locate the Marker Settings Once your chart is selected:
Scroll through the Format pane. Look for the “Markers” section under “Lines” or “Series.” Turn the toggle ON to activate marker options.
4. Start Customizing After enabling markers:
You’ll see options for shape, size, color, border, rotation, and more. These settings apply either to: All markers in the chart, or
We’ll cover how each of those options work in the next sections, with both single-series and multi-series examples.
How to Customize Markers in Line Charts in Power BI Once you’ve enabled markers, you can start making changes to how each data point looks in your line chart. The changes you make can apply to the whole chart, or just specific parts—like a single data series or an individual category on the x-axis.
Let’s walk through two key use cases : single-series and multi-series line visuals.
1. Line Chart with a Single Series Start by creating a basic line chart with one measure (e.g., Net Sales) and no legend. This setup gives you category-level control, meaning you can style each data point along the x-axis independently.
Here’s what you can do:
Shape and Size Choose from several marker shapes (triangle, square, diamond, etc.). Adjust the size using a simple slider or number input.
Rotation Rotate most shapes (except circles) to tilt them for a better visual distinction. For example, rotating a triangle 90 degrees makes it point upward or downward.
Color and Transparency Pick any color for the marker fill. Set transparency to tone down or completely hide the marker. Tip: Setting transparency to 100% makes the marker invisible without deleting it.
Border Styling Add a border to the marker. Customize its color, thickness, and transparency. This helps markers pop out more—especially when your marker fill color is similar to the chart background or line color.
Category-Specific Styling You can also target a single category (e.g., “Brand Eight”) and apply a unique marker style to just that data point. This is handy when you want to highlight a specific point in a time series or a key outlier.
2. Line Chart with Multiple Series Next, try adding another measure (e.g., Gross Sales) to the same line chart. Now the chart includes a legend, and your marker settings switch to series-level control.
Here’s how it works:
You can apply different marker styles to each series. Each series can have its own color, size, and border settings. Any category-level styling done earlier remains intact for the original series. So if you styled “Brand Eight” before adding a second series, that customization is preserved.
This lets you control the look of each series independently; while also maintaining any custom work you’ve already done on specific data points.
3. Show Markers Without the Line If you want to highlight data points without the connecting line, just reduce the line width to zero in the formatting pane. This leaves only the markers visible—perfect for when you want a dot chart or need to avoid clutter from overlapping lines.
You can even apply this trick to only one of the series (e.g., show markers only for Gross Sales, but leave the line visible for Net Sales).
A Simple Guide to Using Markers Without Lines in Power BI Sometimes a line can get in the way. Whether you’re trying to simplify your chart, reduce visual clutter, or focus on just the data points, Power BI gives you a way to remove the lines and keep only the markers.
This trick works especially well when:
You’re working with dense or overlapping data You want to highlight individual values Or you’re aiming for a clean, minimalist visual
Here’s how to do it step by step.
Step 1: Set Up Your Line Chart with Markers Make sure you have a chart ready with markers already enabled. If you haven’t done that:
Create a line chart with at least one measure (like Net Sales) Turn on the Markers option under the visual settings Adjust the marker shape, color, size, or border if needed
Now you’re ready to control the lines.
Step 2: Remove the Line While Keeping the Markers Follow these simple actions:
Still inside the Format pane, find the Lines section You’ll see a setting for Line width Set the line width to 0 (zero): This hides the line completely but leaves your markers untouched If you have multiple series:
You can remove the line for only one series, or Set all series to have zero-line width if you want a full marker-only chart
Example Use Case You have two data series:
Net Sales – keep the line and triangle markers Gross Sales – hide the line, show only square markers
This setup gives your audience an easy way to compare both, without crowding the visual.
How to Customize Markers for Legend-Based Series When your line chart includes a legend field (for example, different product categories, departments, or customer segments), each line in the chart represents a separate group. Power BI allows you to style the markers for each series independently, giving you a lot more flexibility.
This is especially useful when:
You want to make each line more recognizable without relying on just color.
Here’s how to set it up and apply changes step by step.
Step 1: Create a Line Chart with a Legend Add a line chart to your Power BI report. Drag a time field (e.g. Month-Year) onto the X-axis. Drag a numeric measure (e.g. Net Sales) onto the Y-axis. Now, drag a field like Product Category into the Legend section.
Each category will now be shown as a separate line in the chart.
Step 2: Customize Marker Settings Per Series Once your chart has multiple lines based on the legend:
Go to the Markers section. Turn on markers for all series using the top toggle. Now you can apply changes to each series individually:
For example:
Category 1 – Hide its markers entirely by turning off the toggle. Category 2 – Set marker shape to triangle, make size larger. Category 3 – Use squares, change color to blue, increase border width. Category 4 – Choose an X shape, color it violet, and rotate it slightly.
All these changes will only apply to the selected category or series in the legend, giving you fine control over how each group appears.
Tips for Working with Legend Series Stick to distinct marker shapes when multiple lines cross over each other. Increase marker size slightly for the series that matters most. Use rotation to make similar shapes (like triangle vs diamond) easier to tell apart. Color coding helps, but shape and size are more reliable for clarity—especially for color-blind viewers.
Customizing Markers in Scatter Charts in Power BI Scatter charts are built entirely around markers. Each point on the chart represents a combination of two measures (e.g. margin % and discount %) and is often grouped by a category like city or customer.
With the updated marker controls, scatter charts now give you more ways to highlight specific data points, emphasize differences, and style each category uniquely—without having to use complex tricks or custom visuals .
Step 1: Create a Scatter Chart For the X-axis, choose a field like Discount %. For the Y-axis, choose another field like Margin %. Drag a categorical field like City into the Details section. Optionally, use a third measure (e.g. Gross Sales) for the Size field if you want dynamic sizing.
At this point, you’ll see all data points plotted as dots, usually one for each city.
Step 2: Style All Markers or Individual Categories Open the Format pane and go to the Markers section. You now have two main choices:
Option A: Style All Markers at Once Increase the overall marker size to improve readability. Choose a new shape (square, diamond, triangle, etc.). Adjust color, border, or transparency for all points.
Option B: Style a Specific Category Let’s say you want to highlight Los Angeles in your chart.
In the marker formatting panel, look for Category dropdown. Select “Los Angeles” from the list. Apply custom styling: Chage shape to triangle Set a distinct color (e.g. red or violet) Adjust border color and width Set rotation for a more noticeable effect
This custom styling applies only to Los Angeles. All other cities retain the general settings unless you individually style them too.
Dynamic Sizing Based on a Measure
Scatter visuals let you control the size of each marker using a measure.
For example:
Drag Gross Sales into the Size field. Power BI now sizes markers based on that value.
If the markers become too large:
Return to the Format pane → Markers Adjust the size scale range (e.g., lower max size to reduce clutter)
This gives you a good mix of visual encoding—position, size, and shape—all tailored to the data.
Combine Styling Techniques For maximum control, you can:
Show only specific cities using transparency Combine size, color, and borders to differentiate high-value or high-risk items
In short, scatter charts benefit the most from these marker enhancements because they’re 100% marker-based to begin with. You now have full control to turn them into sharp, readable, and purposeful visuals.
5 Tips to Use Marker Enhancements Effectively Avoid over-styling: Just because you can change everything doesn’t mean you should. Stick to a clear visual logic—use shape, color, or size to highlight what matters most. Combine shape and color for better accessibility: This helps users who might have trouble distinguishing colors. A triangle and a square are easier to tell apart than two shades of blue. Use borders on smaller shapes: When using small-sized markers, a contrasting border helps them pop—especially in crowded visuals. Leverage transparency for context: Fade less important points instead of deleting them. This keeps the full picture in view while guiding the audience’s attention. Plan series-level styling before adding more data: If you want unique settings for one series or category, it’s easier to style it before adding more measures or legend fields.

Kanerika’s data visualization experts leverage these advanced marker features to build dashboards that communicate insights instantly.
Where can I find marker settings in Power BI? Marker settings in Power BI are located within the Format pane when a line, area, or combo chart is selected. Click the paintbrush icon to open Format, expand the Visual section, then locate Markers or Data Points depending on your Power BI version. Within this menu, you control marker visibility, shape selection, size adjustments, color options, and border styling. For series-specific settings, expand the individual series dropdown to access dedicated marker controls. Desktop and Service versions maintain consistent navigation paths. Kanerika provides Power BI training that helps teams navigate these settings efficiently for faster report development.
What is a data marker in a chart? A data marker is a visual symbol representing individual data points on line, scatter, or area charts. Each marker corresponds to a specific value intersection between your axis categories and measures, making precise values identifiable within trend lines. Markers transform continuous lines into discrete, scannable data points that viewers can quickly interpret. Common marker shapes include circles, squares, triangles, and diamonds, with sizing and color options adding additional data dimensions. In Power BI, data markers enhance readability, particularly when dealing with overlapping series or sparse datasets. Kanerika designs Power BI dashboards where strategic marker usage improves data comprehension across stakeholder groups.
Can I customize markers for just one data point? Power BI enables single data point marker customization through category-level formatting controls. Select your chart, access the Format pane, and expand the Markers section. Enable the Customize series option, then use conditional formatting rules tied to specific category values or measures to style individual points differently. You can highlight outliers, milestones, or target achievements with distinct colors, sizes, or shapes while maintaining standard formatting elsewhere. This selective approach prevents visual clutter while emphasizing critical data. Kanerika implements conditional marker formatting strategies that draw stakeholder attention to the metrics that matter most.
Can I use different marker shapes for each series? Power BI supports distinct marker shapes for each data series within multi-series line and combo charts. Access the Format pane, expand Markers, then select individual series from the Apply settings dropdown to configure unique shapes. Available options include circles, squares, diamonds, triangles, crosses, and pentagons. This differentiation improves accessibility by providing non-color visual distinction between series, crucial for colorblind users or monochrome printing scenarios. Combining shape variety with color coding creates robust visual hierarchies across complex datasets. Kanerika builds accessible Power BI reports using series-level marker customization that ensures clarity for all audience segments.
How do I remove the line and keep only markers? Creating a marker-only chart in Power BI requires modifying line stroke settings within the Format pane. Select your line chart, open Format, navigate to the Lines section, and set stroke width to zero or toggle line visibility off. Alternatively, switch to a scatter chart visual that inherently displays only markers without connecting lines. Keep markers enabled under the Markers section with your preferred shape and size settings. This approach creates clean dot plots ideal for displaying discrete categorical comparisons without implied continuity. Kanerika configures Power BI visuals tailored to your specific analytical needs, including custom marker-only presentations.
What's the difference between category-level and series-level styling? Category-level styling in Power BI applies formatting to specific data points across all series based on axis categories, such as highlighting December values regardless of which measure they represent. Series-level styling formats all data points within a single measure uniformly, like coloring an entire Revenue line blue with square markers. Category-level targets horizontal slices of your chart while series-level targets vertical data groupings. Combining both approaches creates sophisticated visual hierarchies where certain time periods and specific metrics receive distinct treatment simultaneously. Kanerika’s visualization specialists implement layered styling strategies that maximize insight extraction from complex Power BI dashboards.
How to change tick marks in Power BI? Tick marks in Power BI axes are modified through the Format pane under X-axis or Y-axis settings. Select your visual, open Format, expand the relevant axis section, and locate gridline and tick mark controls. Adjust tick positioning between inside, outside, or crossing options, and modify tick length, color, and weight to match your design standards. For categorical axes, tick placement aligns with category labels while continuous axes offer interval-based tick distribution. Proper tick mark configuration improves chart readability and professional appearance. Kanerika establishes Power BI style guides ensuring consistent axis formatting across enterprise report portfolios.
How to insert a line with markers? Inserting a line chart with markers in Power BI starts by selecting the Line chart visual from the Visualizations pane and adding your data fields. Once the chart renders, click into the visual, open the Format pane, and expand the Markers section. Toggle markers to On and configure shape, size, and color preferences. For combo visuals, ensure your measure is assigned to the line values well rather than column values. Markers appear automatically at each data point intersection along your trend line. Kanerika builds customized Power BI report templates with pre-configured marker settings that accelerate dashboard development.
How to change markers in a line graph? Changing markers in a Power BI line graph requires accessing the Format pane after selecting your visual. Navigate to the Markers section, where you can modify shape, size, color, and border properties. Use the Apply settings dropdown to change markers globally or target specific series individually. For dynamic changes, apply conditional formatting rules that adjust marker appearance based on underlying measure values or thresholds. Experiment with marker sizes between 5 and 8 pixels for optimal visibility without overwhelming your data lines. Kanerika optimizes Power BI line graph configurations to balance aesthetic appeal with analytical clarity across enterprise dashboards.
How to annotate Power BI? Annotating Power BI reports involves adding text boxes, shapes, and images that provide contextual explanations alongside your visuals. Use the Insert menu to add text boxes for commentary, or leverage the Analytics pane to add reference lines with labels marking targets or thresholds. For dynamic annotations, create card visuals displaying conditional text using DAX measures that respond to data changes. Power BI also supports comment threads for collaborative annotation during report review processes. Strategic annotations transform dashboards from data displays into guided analytical experiences. Kanerika implements annotation strategies that enhance report self-service capabilities for business users.
What is the highlight function in Power BI? The highlight function in Power BI enables cross-visual filtering where selecting data in one visual emphasizes related data points across other visuals on the same page. When highlighting activates, unrelated data appears grayed out while connected values retain full color saturation, including their markers. Configure highlight behavior through Visual interactions settings accessible via the Format menu. This feature works alongside marker enhancements to draw attention to specific data segments during interactive analysis sessions without completely filtering out contextual information. Kanerika designs interactive Power BI dashboards leveraging highlight functionality for intuitive exploratory data analysis experiences.
How to modify tooltips in Power BI? Modifying tooltips in Power BI enhances marker interactions by displaying richer information on hover. Access tooltip settings through the Format pane under Tooltips, where you enable or disable them and adjust background color, text formatting, and transparency. Add additional fields to tooltips by dragging measures into the Tooltips field well, providing context beyond what markers visually represent. For advanced customization, create report page tooltips that display entire mini-reports when hovering over data points. Custom tooltips paired with enhanced markers create layered information delivery. Kanerika develops Power BI solutions with sophisticated tooltip configurations that maximize insight density per visual interaction.
What is the enhanced PBIR format? The enhanced PBIR format represents Power BI’s improved report definition structure that separates visual configurations, including marker settings, from data model definitions. This JSON-based format enables better version control integration, easier collaboration through merge-friendly file structures, and programmatic report manipulation. Enhanced PBIR stores marker enhancements, conditional formatting rules, and styling configurations in readable text files rather than binary blobs. Organizations adopting this format gain improved DevOps workflows for Power BI development with cleaner change tracking across report iterations. Kanerika helps enterprises implement modern Power BI development practices using enhanced PBIR for scalable, maintainable BI solutions.
