In this tutorial, Devin Knight demonstrates how to utilize the Aster Plot, a unique Power BI Custom Visual. Unlike traditional Pie or Donut charts, the Aster Plot introduces the innovative capability to use two separate measures, allowing you to control both the angle sweep and depth of each segment for enhanced data visualization.
The Aster Plot is a distinctive and powerful visualization tool that creatively merges the characteristics of both pie charts and donut charts. Unlike traditional pie or donut charts, which primarily focus on displaying proportions of categories based on a single metric, the Aster Plot introduces an additional dimension. This unique feature enables users to apply a secondary measure that dynamically influences the sweep angle of each slice within the chart. By incorporating this dual-measure capability, the Aster Plot allows for a much richer and more insightful comparison of data categories.
At its core, the Aster Plot displays categorical data in a circular layout where each segment represents a different category. The radius or length of each slice reflects the value of one measure, while the angle or arc length corresponds to the second measure. This combination creates a multidimensional perspective in one compact visualization, making it easier for analysts, business intelligence professionals, and decision-makers to discern subtle differences and patterns that might be missed with simpler charts.
How the Aster Plot Enhances Data Interpretation
Traditional pie charts are effective for showing proportions but can become cluttered or difficult to interpret when there are many categories or when categories have values close in size. Donut charts offer a similar approach but often lose the ability to convey detailed secondary information. The Aster Plot, on the other hand, overcomes these limitations by introducing two key variables into a single visual representation.
The dual-measure approach means that viewers can instantly grasp not just the relative size of a category but also its weight in terms of a second dimension. For example, in sales analysis, the first measure might represent total revenue per category, while the second measure could illustrate profit margin or units sold. This enriched context enables users to quickly identify high-revenue categories with low profitability or vice versa, making strategic decisions more informed and data-driven.
Practical Applications of the Aster Plot in Business Intelligence
The versatility of the Aster Plot makes it a valuable addition to any business intelligence toolkit. It is particularly useful in scenarios where multiple factors influence the performance of categories. Marketing analysts can use it to compare campaign effectiveness not only by reach but also by engagement rate. Supply chain managers might analyze vendor performance by order volume combined with delivery punctuality. Financial analysts can evaluate investment portfolios by both asset allocation and risk exposure simultaneously.
By integrating this visual into Power BI dashboards, users benefit from a more interactive and visually appealing experience. The Aster Plot allows for quick identification of outliers, trends, and correlations that would otherwise require more complex data manipulations. This ability to simultaneously visualize two measures on one chart significantly enhances decision-making efficiency and clarity.

Once the data is linked, the visual automatically adjusts to depict the categories according to their values, creating an intuitive representation that is easy to interpret. Users can customize colors, labels, and tooltip information to match their branding or reporting style, further enhancing readability.
Moreover, the Aster Plot supports interactivity, allowing users to drill down into specific categories or cross-filter other visuals on the report page. This dynamic aspect makes the Aster Plot not just a static chart but a critical element in exploratory data analysis.
Why Choose the Aster Plot Over Other Visualization Options?
While there are many visualization types available, the Aster Plot stands out due to its capacity to display multi-dimensional data succinctly without overwhelming the viewer. Unlike bar charts or scatter plots, which often require more space or multiple visuals to convey the same information, the Aster Plot consolidates dual metrics into one cohesive graphic.
This compactness makes it ideal for executive dashboards, where space is limited but decision-makers require quick insights across multiple categories. Furthermore, the visually striking nature of the Aster Plot attracts attention and encourages engagement, which can improve comprehension and retention of critical information.
Unique Characteristics That Set the Aster Plot Apart
The Aster Plot’s blend of radius and sweep angle encoding offers a visually balanced yet information-dense display. This rare combination is seldom found in standard visualization libraries, making it a specialized choice for advanced users looking to elevate their reporting capabilities.
In addition, the visual’s ability to highlight nuances between categories by visually emphasizing differences in two dimensions simultaneously enhances storytelling. This makes the Aster Plot especially useful for presentations where illustrating complex relationships clearly is paramount.
Enhancing Your Power BI Dashboards with the Aster Plot
Incorporating the Aster Plot into Power BI dashboards adds a layer of sophistication and insight that enriches the overall analytical narrative.

Distinctive Attributes of the Aster Plot Visual
The Aster Plot visual stands out as a sophisticated chart that leverages the power of dual measures to portray data with enhanced clarity and dimensionality. This visual employs up to two distinct quantitative metrics to communicate nuanced information about categorical data sets. The first metric primarily governs the depth or length of each individual category slice within the circular plot. This means that the radius extending outward from the center of the plot directly corresponds to the magnitude of this first measure, enabling viewers to quickly assess the relative size or intensity of each category based on this parameter.
Complementing this, the second metric influences the width or angular sweep of each slice. Instead of having all slices evenly spaced like a traditional pie chart, the Aster Plot allows this angular span to vary according to the value of the second measure. This dynamic modulation of slice width introduces an additional dimension to the visual, making it possible to represent two separate but related metrics simultaneously. This dual encoding is especially valuable for analysts seeking to understand complex relationships within their data, where one measure provides an absolute scale and the other a comparative scale.
For instance, consider a business intelligence report on product categories where the first measure represents total sales volume, while the second measure could represent profit margin percentage. In this case, a slice may be long (high sales volume) but narrow (lower profit margin), or vice versa. Such visual distinctions afford users a granular view that neither a simple pie chart nor a bar chart could effectively convey on its own.
This dual-measure characteristic enhances the interpretability of the data by making differences between categories more apparent and by enabling rapid identification of outliers or patterns that require deeper investigation. When multiple categories are displayed, the interplay of depth and width creates a visually engaging and insightful story that drives data-driven decisions.
Extensive Customization Features in the Format Pane
One of the compelling strengths of the Aster Plot visual lies in its extensive customization capabilities, accessible through the Power BI Format pane, often referred to as the Format paintbrush. These options empower users to tailor the appearance and functionality of the visual to perfectly align with the thematic and aesthetic requirements of their reports.
Control Over Legend Presentation
The legend serves as a crucial guide for interpreting the categorical slices of the Aster Plot. Our site’s version of the Aster Plot allows you to enable or disable the legend display positioned above the visual to optimize the use of report real estate and maintain visual harmony. Users can effortlessly adjust the legend’s position, shifting it to the left, right, top, or bottom, depending on the layout preferences and design consistency with the rest of the dashboard.
The ability to toggle the legend title on or off provides additional flexibility, allowing the report creator to either include descriptive context or keep the visual clean and minimalistic. When enabled, the legend title text can be customized, offering the option to rename it to a more descriptive or contextually relevant label.
Furthermore, the legend text size and color can be modified to enhance readability and complement the overall color scheme of the report. This is particularly beneficial for ensuring accessibility and catering to diverse audiences with varying visual preferences.
Detail Label Enhancements
The Aster Plot visual includes a feature that lets you activate detail labels, which display precise data values adjacent to each slice. This feature is invaluable when precise numerical data must be conveyed alongside the visual representation for better clarity. Users can fine-tune these labels by customizing their color, text size, and number formatting.
Customization of label colors helps maintain brand consistency or simply enhances contrast against the background for improved visibility. Adjusting text size allows labels to be more prominent or subtle, based on the design needs and the density of information presented. Additionally, number formatting options such as decimal places, currency symbols, or percentage formats ensure that data is displayed in the most meaningful and professional manner.
Outer Line and Border Customization
To further augment the visual distinction of the Aster Plot, an outer line feature is available. This option adds a bold, circular black border encircling the entire plot, effectively delineating it from other elements on the report page. This border accentuates the visual’s boundaries, improving focus and preventing it from blending into adjacent visuals or backgrounds.
Users can adjust the thickness of this outer line, enabling subtle emphasis or bold framing according to personal preference or report design requirements. This customization option is particularly useful in busy dashboards where clear visual separation aids user comprehension and prevents cognitive overload.
Additional Formatting Flexibility
Like other Power BI visuals, the Aster Plot offers further customization in terms of background color, border application, and aspect ratio locking. Changing the background color allows the visual to seamlessly blend with or stand out against the report’s overall color palette. Borders can be applied not only around the plot but also to individual slices, depending on the version, adding another layer of visual segmentation.
Locking the aspect ratio ensures that the Aster Plot maintains consistent proportions regardless of resizing, preserving the integrity of the visual representation across various screen sizes and devices. This feature is crucial for maintaining visual accuracy and preventing distortion, especially when sharing dashboards with stakeholders on different platforms.
Practical Benefits of the Aster Plot Visual’s Customization
The broad spectrum of customization options elevates the Aster Plot beyond a mere data visualization tool into a highly adaptable instrument for storytelling with data. By personalizing legends, labels, borders, and colors, users can create visuals that are not only informative but also aesthetically aligned with their corporate branding or thematic report designs.
