How to Enable Build a Visual in Power BI

Creating your first visual in Microsoft Power BI is the moment where raw data starts to tell a story. This guide will walk you through the essential steps, from selecting your chart type to customizing it, making the process feel less like a technical chore and more like a creative exercise. We'll start with a simple bar chart and explore how flexible Power BI is for transforming your data into clear, effective visuals.

Understanding Your Power BI Workspace

Before you build, it helps to know your way around the workshop. When you open Power BI Desktop with your data already loaded, you'll see three primary panes that you'll use constantly. Getting familiar with them now will make the creation process much smoother.

Think of your screen as being divided into three key areas:

• The Fields Pane (Right): This is your data library. After you've connected to a data source (like an Excel sheet or a database), all your tables and their corresponding columns (or "fields") will appear here. This is where you'll grab the ingredients for your visualizations.
• The Visualizations Pane (Middle-Right): This is your toolbox. It contains icons for all the different types of charts and graphs you can create, from standard bar charts and pie charts to maps and funnel charts. This pane also includes formatting and analytics options once you've created a visual.
• The Canvas (Center): This is your blank report page. It's the main stage where your data visuals will come to life. You'll drag fields onto this canvas and arrange your charts to build your report.

For a visual to work, you need data. This guide assumes you’ve already connected to a data source and can see your tables in the Fields pane. If you haven't, a simple Excel file with a few columns like 'Product,' 'Region,' and 'Sales' will work perfectly for following along.

Creating Your First Visual: A Simple Bar Chart

Let's build one of the most common and effective visuals: a bar chart. We'll create a chart that shows sales performance across different product categories. This process is foundational and applies to building almost any other visual in Power BI.

Step 1: Select Your Visual Type First

The clearest way to start is by telling Power BI what you want to build. Look at the Visualizations pane and find the icon for the "Stacked bar chart" or "Clustered bar chart". Clicking on any of these icons will place an empty, greyed-out visual placeholder onto your canvas. This acts as a container, waiting for you to add data.

Starting this way ensures you know exactly which type of visual you're building from the get-go. Power BI is flexible, though, you can also start by selecting data fields, and Power BI will guess which visual to use (usually a table or bar chart).

Step 2: Add Data Fields to the Visual

With your grey placeholder selected (it will have a border around it), look back at the Visualizations pane. Below the icons, you’ll see specific "wells" or bins like Y-axis, X-axis, and Legend. These are the slots where you'll drag and drop your data fields.

Let's map our data to the chart:

• From your Fields pane, find the field that represents your product categories (e.g., 'Product Category'). Click and drag it into the Y-axis well. You'll see the canvas update immediately, showing the product categories listed along the vertical axis of your empty chart.
• Next, find your sales data (e.g., 'Sales Amount'). Click and drag this field into the X-axis well. Instantly, Power BI calculates the total sales for each category and draws the bars, bringing your chart to life.

That's it! In just a few drags and drops, you've created a meaningful bar chart. The real power comes in refining and customizing this visual to make it even more insightful.

Customizing and Formatting Your Visual

A default chart gets the point across, but proper formatting makes it professional, readable, and perfectly aligned with your intended message. To start formatting, make sure your visual is selected on the canvas, then click on the little paintbrush icon in the Visualizations pane. This opens up the "Format visual" tab.

Editing Titles, Axes, and Labels

Clear labels are non-negotiable for an understandable chart. Power BI often creates default titles based on the fields you used, which are functional but can be improved.

• Title: Under the "Format visual" tab, find the "General" section and expand "Title." You can rewrite the text to be more descriptive. For example, change "Sum of Sales Amount by Product Category" to something clearer like "Total Sales by Product Category." You can also adjust font, size, and alignment here.
• Axes: Back in the "Visual" section of formatting, you can expand the X-axis and Y-axis options. Here, you can toggle titles on or off, change font colors, and adjust the scale if needed. Small adjustments can greatly improve readability.
• Data Labels: Sometimes it's helpful for your audience to see the exact numbers without hovering over each bar. In the "Visual" section, find the "Data labels" toggle and switch it on. The sales amount will now appear directly on or next to each bar on your chart.

Adjusting Colors and Design

Color is a powerful tool for branding and guiding attention. By default, Power BI uses a standard color theme, but you shouldn't feel restricted by it.

• Bar Colors: In the "Visual" formatting section, find the "Bars" (or "Columns" for a column chart) tab. Here, you can change the color of all bars at once or click "Show all" to assign a unique color to each product category. Use branding colors or colors that have a specific meaning in your business (e.g., green for high-performing categories, red for low).
• Background and Borders: In the "General" formatting section under "Effects", you can add a subtle background color, a visual border, or even a shadow to help your visual stand out on a crowded dashboard. Use these effects sparingly to avoid creating visual clutter.

Thinking Outside the Bar: Changing A Visual's Type

One of the best features of Power BI is the ability to instantly see your data in a new light. Let's say you want to see which product category contributes the largest share of total sales. A pie chart is better suited for showing parts of a whole.

You don't need to rebuild anything. Simply follow these steps:

1. Select your existing bar chart on the canvas.
2. In the Visualizations pane, click on the icon for the "Pie chart" or "Doughnut chart."

Power BI will automatically convert your bar chart into a pie chart, remapping the fields appropriately. 'Product Category' is now used for the legend (the slices), and 'Sales Amount' determines the size of each slice. This effortless transformation encourages experimentation, allowing you to find the most effective way to present your insight.

Pro Tips for Creating Exceptional Visuals

Building a chart is one thing, building an effective chart is another. Keep these best practices in mind to make your Power BI reports truly impactful.

• Keep It Simple: Each visual should communicate one primary insight. Don't try to cram too much information into a single chart. If you have multiple stories to tell, create multiple visuals.
• Choose the Right Chart for the Data: Your choice of visual should be intentional. Use bar or column charts for comparing values across categories, line charts for tracking trends over time, and scatter plots for exploring relationships between two numerical values. Reserve pie and doughnut charts for showing composition when you have less than six or seven categories.
• Tell a Story with Your Dashboard: Think about how your visuals will work together on a single report page. Arrange them logically to guide your user's eye from a high-level overview to more granular details. Use slicers (a type of filter visual) to make your report interactive, allowing users to drill down into the data that matters most to them.
• Focus on Readability: Ensure your fonts are large enough, your colors have sufficient contrast, and your labels are clear. The goal is communication, if your audience struggles to read your chart, your message will be lost.

Final Thoughts

Building visuals in Power BI is a process of selecting a chart type, dragging and dropping your data in the right places, and using the formatting tools to enhance clarity and impact. With a bit of practice, you’ll be quickly turning spreadsheets of data into compelling visual stories that drive a better understanding of your business.

While mastering a powerful tool like Power BI is a great skill, sometimes you need insights without the steep learning curve. We built Graphed for this very reason.
