What is a Power BI Dashboard?

A Power BI dashboard is a consolidated display of key metrics, insights, and visualizations that provide a comprehensive overview of your data-driven objectives. It serves as a dynamic, real-time interface that allows you to monitor performance, track trends, and make informed decisions. By combining various visual elements such as charts, graphs, and maps, Power BI dashboards transform complex datasets into easily comprehensible insights, fostering a deeper understanding of your organization's data landscape. Power BI dashboards offer a centralized hub to transform raw data into actionable intelligence, whether used for sales tracking, operational analysis, or strategic planning.

A Power BI dashboard is a consolidated interface that combines various data visualizations, reports, and key performance indicators (KPIs) in a single, interactive interface. It provides a high-level overview of the most crucial insights from your data, allowing users to quickly grasp trends, patterns, and important metrics at a glance. For instance, imagine a retail company aiming to monitor its sales performance. A Power BI dashboard could showcase real-time sales figures, top-selling products, geographic distribution of sales, and year-over-year growth. Color-coded charts, graphs, and maps could visually represent this information, making it easy for executives to assess performance and make strategic decisions promptly.

How to Create a Dashboard in Power BI?

Creating a dashboard in Power BI involves a series of steps that blend data preparation, visualization design, and interactivity. Here's a step-by-step guide to help you build your own Power BI dashboard:

Step - 1:

Launch Power BI Desktop, click "Home," and select "Get Data" to connect to your data sources, such as Excel, SQL Server, or cloud services like Azure. In this illustration, we will employ an Excel spreadsheet encompassing a sales dataset from US superstores in 2015, as shown in the figure below. Once data is loaded, you can also clean and transform your data as needed using the Power Query Editor. This may involve filtering, merging, or reshaping data.

Step - 2:

After loading and transforming your dataset into Power BI, go to the Visualizations pane on the right, select the desired visualization type (e.g., bar chart, pie chart, map), and drag and drop fields from your dataset to the appropriate areas in the Power BI visualization canvas. In this instance, we've created a line and stacked bar chart to depict monthly profits and sales, respectively. Additionally, there are two donut charts portraying the combined sales based on customer segments and total profit categorized by shipping modes. Furthermore, the dashboard incorporates two cards detailing the overall sales and profits. You can also choose to personalize your visualizations, including aspects like font choice and color palette.

Step - 3:

You can also add interactive elements like slicers, filters, and drill-through options to the Power BI report. These interactive elements empower users to dynamically explore and analyze data, enabling focused insights and customized views for more informed decision-making. For instance, we have applied a slicer to filter reports/visualizations based on the region attribute, as shown in the figure below. Before proceeding to the next step to build and publish your dashboard, ensure you save your report onto your local disk.

Step - 4:

Up to this point, you were using Power BI Desktop to design and craft various visualizations in your report. To build the dashboard, you will require Power BI Service (Online). Click the "Publish" option located in the Home tab's ribbon to save your report to the Power BI service (online platform), as shown in the figure below.

Step - 5:

By clicking the link shown in the above figure, it will redirect to your web browser, and you can access your dashboard in the Power BI service (online). Once there, you have the option to export the dashboard to formats such as PPTs, PDFs, etc., along with the ability to share it with colleagues and teams, as shown in the figure below.
