What are Small Multiples?
Multiple instances of the same visual, side-by-side in different dimensions, are known as small multiples. This helps compare data across many segments at a glance. For instance, you can split a sales performance card visual by region, product category, or time to give a holistic view of your data.

Managing stock levels dynamically is essential for effective inventory management. A crucial aspect of this task involves calculating cumulative quantities to track the balance of products over time. In this example, we have Sales and Purchasing tables, and we aim to create a Matrix visual in Power BI to display the purchased and sold quantities accurately. The ultimate goal is to dynamically track the stock balance (leftover products) at any given point by calculating the difference between cumulative purchases and cumulative sales.
