Understanding the concept of small multiples in data visualization
Small multiples, also known as trellis charts or panel charts, are a series of small and similar charts that display different subsets of data in a grid-like format. Each chart represents a different slice of the same data, allowing the viewer to easily compare and contrast different data points. Small multiples are a great way to display complex data sets in a way that is easy to understand and analyze. They give a quick overview of the data without overwhelming the viewer with too much information at once.
Small multiples are particularly useful when analyzing trends over time or comparing data across different categories. For example, a small multiple chart could display the sales figures for different products in a company’s portfolio over the course of a year. By displaying each product’s sales figures in a separate chart, the viewer can easily see which products are performing well and which ones are struggling. Small multiples can also be used to compare data across different regions or demographics, making them a versatile tool for data visualization.
Benefits of using small multiples in Power BI
There are many benefits of using small multiples in Power BI. One of the most important is that they allow you to visualize multiple aspects of your data set at once, making it easier to see trends and patterns. Since each chart is showing a subset of the same data set, you can quickly see how different parts of your data relate to each other. This is particularly useful when working with large and complex data sets, where it can be difficult to identify patterns and trends without spending a considerable amount of time analyzing the data.
Another benefit of using small multiples in Power BI is that they can help you to identify outliers and anomalies in your data. By comparing the charts side by side, you can quickly spot any data points that are significantly different from the rest. This can be particularly useful when working with financial data, where anomalies can indicate errors or fraudulent activity.
Finally, small multiples can also help you to communicate your data more effectively to others. By presenting multiple charts in a clear and concise way, you can help your audience to understand complex data sets more easily. This can be particularly useful when presenting to non-technical stakeholders, who may not have the same level of expertise in data analysis as you do.
Step-by-step guide to creating small multiples in Power BI
Now that you understand the concept of small multiples and their benefits, let’s dive into how to create them in Power BI. Here’s a step-by-step guide:
- Open Power BI and select the “New Report” option.
- Select the data set you want to use from the left-hand side of the screen.
- Select a chart type that supports the small multiples feature from the visualizations pane on the right-hand side of the screen.
- Drag and drop the fields you want to display in your small multiples from the Fields pane to the Values area in the visualization pane.
- Customize your charts to your liking by choosing different chart types, colors, and layouts from the visualizations pane.
It’s that simple! In just a few clicks, you can create your own small multiples to visualize and analyze your data.
One important thing to keep in mind when creating small multiples in Power BI is to choose the right fields to display. You want to make sure that the fields you choose are relevant to the analysis you want to perform and that they can be easily compared across the different charts. It’s also a good idea to limit the number of fields you display in each chart to avoid clutter and confusion.
Exploring different chart types for small multiples in Power BI
Power BI offers a variety of chart types that can be used in small multiples, each with its own advantages and disadvantages. Let’s explore some of the most common chart types:
- Line charts: great for showing trends and changes over time.
- Bar charts: ideal for showing comparisons between different data points.
- Area charts: similar to line charts, but fill in the area below the line, making it easier to see changes in data.
It’s important to note that while pie charts are a valid chart type in Power BI, they typically do not support the small multiples feature. Always choose the chart type that best represents your data and makes it easy for the viewer to understand.
Tips for choosing the right data for small multiples in Power BI
Choosing the right data to display in small multiples is key to their effectiveness. Here are some tips to keep in mind:
- Focus on a specific aspect of your data to avoid displaying too much information at once.
- Select data that has a clear correlation to avoid confusion when comparing charts.
- Avoid using too many small multiples on one screen to prevent clutter.
- Use consistent scales on all charts to ensure an accurate comparison between data points.
By keeping these tips in mind, you can create small multiples that are clear, concise, and easy to understand.
Customizing small multiples in Power BI: Colors, fonts, and layout options
Power BI offers a variety of customization options for small multiples, allowing you to create a personalized look and feel for your charts. Some customization options include:
- Choosing different color themes.

By customizing your small multiples, you can create charts that are not only useful, but visually appealing as well.
How to filter and drill-down into small multiples in Power BI
Power BI allows you to drill down into your small multiples to explore your data in more detail. You can filter your data by selecting specific values or categories, allowing you to see how individual data points contribute to the overall picture. To filter or drill down into your small multiples, simply right click on the chart and select “Filter” or “Drill Down” from the context menu.
Best practices for designing effective small multiples in Power BI
Now that you understand how to create small multiples in Power BI, here are some best practices to keep in mind:

Comparing small multiples with other chart types in Power BI
While small multiples are a powerful tool for data visualization, they are not always the best option. Let’s compare small multiples with some other chart types:
- Single chart: Ideal when you want to display just one data set or comparison in detail.
- Combination chart: Useful when comparing multiple data points that have different scales or units of measure.
- Heat map: Great for displaying correlations between different data points or categories.
It’s important to choose the right chart type for your data set and communication needs.
