Power BI is an increasingly popular business intelligence and visualization tool from Microsoft that enables data analytics and data visualization. Ron George initially designed Power BI in the summer of 2010. The initial release was available for public download the following year. Power BI Desktop, Power BI Service, Power BI Gateway, Power BI Report Server, and Power BI Mobile Apps are the key components of the platform.
In this article, we’ll discuss the basics of Power BI Desktop and how to create a Power BI dashboard using Power BI Desktop. Then, we’ll publish this dashboard on Power BI Service.
What is Power BI?
Microsoft’s Power BI is a business and data analytics service that enables professionals to process, analyze, and visualize vast volumes of data. It helps extract insights, draw conclusions, and share results in the form of reports and dashboards across various departments. It provides an easy drag and drops feature with a range of interactive data visualizations to generate reports and dashboards.
Features of Power BI
- Power BI is faster and performs better when there is a smaller volume of data
- Power BI provides an interface based on Microsoft Office 365 that is user-friendly, intuitive, and easy to understand
- Using Power BI, you can work with several data sources, such as Excel, Text/CSV, JSON, SQL Server databases, IBM DB2, MySQL, etc.
- Power BI can connect with the R programming language, and it also supports various Data Analysis Expression (DAX) functions and measures
- Power BI has functional integration with the Microsoft Azure cloud platform. It helps to analyze insights and patterns in datasets
What is a Power BI Dashboard?
Power BI dashboards are single-page documents, often referred to as canvas, which illustrate a story through visualizations. A well-designed dashboard consists only of the highlights of a story. This is due to the fact that it is limited to one page. For more information, readers can view related reports. Power BI is the only service that offers dashboards.
A single page visualization with multiple charts and graphs to tell a story is called a Power BI dashboard. This one-page visualization in a dashboard is also known as a Canvas. The Power BI dashboard is a feature only available in Power BI Service. Since a Power BI dashboard is limited to one page, it only contains the highlights of a story. You cannot create a dashboard on Power BI Desktop.

How to Create a Dashboard in Power BI?
Building reports on Power BI Desktop and publishing them to Power BI Service is one of the best ways to understand how a Power BI dashboard works.
For our demo, we’ll be looking at a sales dataset that contains product sales information throughout the United States. The dataset contains various customer-related details, including customer names, order and shipment dates, product names, product categories and subcategories, profit made, and so on. This dataset is commonly known as a Sample Superstore dataset. We’ll analyze this dataset to compare sales and profit from each segment, year, and quarter.
We’ll also create a map to show the sales across different states in the USA.
The following is the dataset that we’ll be using to create the dashboard:
Fig: Sales Data
First, we will create three separate cards to calculate the total sales, profit, and quantity sold. From the visualization panel on the right, click on “card,” which will create an empty card.
Drag the sales column on to the fields, which will give you the total amount of sales of all products. You can edit this card by changing the font size and the color of the sales value. Also, you can add a title to this card. Similarly, you can create two more cards for total profit and total quantity sold by dragging respective columns on to fields.
After that, we’ll add a slicer to our visualization to slice the data based on the “Order Date” column. This will help us filter the data and view it according to the need.
Fig: Cards and Slicers
Suppose you are looking to visualize and analyze sales and profit over a certain number of years. In order to do this, you’ll create a line and stacked column chart. Select the line and stacked column chart from the visualization panel and drag the “Order Date” column on to “Shared Axis.” Put “Sales” under “Column” values, and insert the “Profit” column into “Line” values. That will generate the graph. You can edit the color of the bars and the line under the format tab.
In the chart above, the bars represent the sales, and the line represents the profit. The graph reveals that the highest amount of sales and profit occurred in 2017.
Power BI Desktop provides an excellent feature to drill down into the data and visualize the graph in terms of each quarter, month, and day. This option is available at the top when you navigate to a specific chart.
Fig: Sales and profit by each month
From the visualization above, we can see that November had the most sales.
You can also add the labels to the graph by clicking the “Format” tab and switching on the data labels.

Now, let’s create a clustered column chart by analyzing annual and quarterly sales.
From the Visualizations menu, select the “Clustered Column Chart.” Add the “Year” column onto the axis. Take the “Quarter” columns under “Legend,” and add the “Sales” columns to “Value.”
Fig: The clustered bar chart
The graph above shows that the first quarter of every year had the lowest sales numbers, while the fourth quarter was consistently the highest. You also have the option to change the colors on your graph to make it more visually appealing.
Now, let’s analyze the sales for each state in the US. To do this, we’ll use a filled map. Select a filled map from the visualizations panel. Add the “State” column to “Location.” Drag the “Sales” column onto “Tooltips.” To edit the colors, click on the “Format” tab, and choose “Data Colors.” Select the conditional formatting option and add the range of colors that you’d like.
Fig: Formatting colors based on the sales
We have defined our color scheme for the lowest, middle, and highest sales values. The states colored green made the lowest amount of sales. The states marked in orange or red, which are California, Texas, and New York, made the highest amount of sales. Similarly, you can also build a map to see the profit and the units that each state sold.
Fig: Sales by each State
The following is what our report looks like so far. We have gone over creating cards, slicers, line and clustered column charts, clustered bar charts, and filled maps.

Next, let’s look at how to create a donut chart to analyze sales and profit by segment.
Under visualizations, click on the donut chart. Under legend, add the segment column. Drag the “Sales” column on to “Values” and “Profit” on to “Tooltips.”
Fig: Donut chart for Sales and Profit
The donut chart above indicates that the consumer segment had the highest amount of sales and profit, while the home office segment had the lowest. You can format the visualization as per your requirements to make it more visually attractive.
Now, we’ll move on to creating a pie chart, which will enable us to visualize the sales for each product category. Move the “Category” column on to “Legend” and add the “Profit” column under “Values.” Drag the “Sales” column on to “Tooltips.”
Fig: Pie Chart for Profit and Sales
The technology category generated the highest amount of sales and profit, while furniture made the lowest. The “format” tab is used to change the colors and make any necessary edits.
The following is what the final overall sales report will look like:

Let us now visualize our data at a more granular level by analyzing sales, profit, and units sold at regional and state levels.
First, we’ll create three slicers to filter our data. Click on the slicer from the visualizations panel and add the “Region” column on to “Field” to create a regional slicer. Similarly, you can create a state and year slicer. You also have the option to edit the slicers to change the font size, increase the size of the text, and add a background color.
Fig: Slicers to filter data
We’ll now create a table to check the quantity and the profit made in each city. Under the “Visualizations” tab, select “Table”. Add the “City” column under “Values,” followed by quantity and the “Profit” column. Add a background color to the column headers and increase the size of the font. You can filter the data by selecting the items from each of the slicers.
Below, we have selected the central region and selected the state of Minnesota. In the table, you can see all the cities in the state of Minnesota, the quantity sold, and the profit they made.
Fig: Creating a Table in Power BI
Sorting a table is another capability that Power BI Desktop supports. This gives users the option to sort the column in a table in their order of preference.
Now, let’s build a clustered bar chart to analyze the sales for each product category across different states. Select the clustered bar chart from the visualizations panel. Take the “State” column on the axis, “Category “columns on to the legend, and “Sales” on to “Value.”
Fig: Clustered Bar Chart
Among the three categories of products, the state of California made the highest sales for all categories.
Next, let’s verify the annual profit by category using an area chart. Select the area chart from visualizations and drag the “Year” column on to the axis, the “Category” column on to the legend, and “Profit” on to “Values.”
Fig: Area chart using Power BI
You can analyze the profit and quantity that each product category and subcategory sold. You can also create a funnel. Users can explore their many options through the dashboard.
The following is what our report for the region and state-level analysis will look like::
Fig: Region and State Level Report
If you want to go in detail and create a more granular level report, you can do that by creating a report based on the products’ categories and subcategories, as shown in the report below. You can use category and subcategory as your slicers and create different line charts, bubble charts, treemaps, and pie charts to visualize the data.
Fig: Category and subcategory Level Report
We’ll now publish our overall sales report on Power BI Service and create a dashboard.
Save your reports on Power BI Desktop. Then, click on the home menu and select the “Publish” button.
