This Power BI tutorial focuses on effectively using the funnel chart to visualize data flow through a process. The video begins by demonstrating how to import data from an Excel file containing three sheets: monthly expenses, profit and loss, and selection data. The selection data is then used as a straightforward example to create a basic funnel chart, illustrating a candidate selection process from total applicants to those finally chosen for an interview. This initial example clearly shows how a funnel chart displays decreasing values at each stage of a process, highlighting percentages at each step, such as the 18.8% of female candidates (between 18-45 years old) selected.
The tutorial then moves on to more complex scenarios, showcasing how to adapt data for funnel chart visualization. For profit and loss data, where costs and expenses are present but shouldn’t be directly on the chart, the video demonstrates using filters to display only relevant financial metrics like revenue and net profit. Finally, the most intricate example involves monthly salary and expenses data, which requires significant transformation. This involves using Power Query to add an index column, creating a new column to convert expenses into negative values, and then calculating a “savings” column using the CALCULATE and FILTER functions to determine running totals. The description column is also transformed to provide more meaningful labels for the savings figures. This transformed data is then successfully visualized on a funnel chart, clearly showing the remaining amount after each expense, culminating in the final savings percentage.
