IGLOO BI

In the previous post, we covered the basic concepts of Dynamic Format Strings in Power BI. In this installment, we take it a step further by introducing core patterns used directly in the field: • “Reports where units change automatically based on the indicator (KPI)” • “Advanced design that expresses both % and currency within a single column” In practice, I have seen many cases where reports become unnecessarily complex due to these requirements. Especially as the number of KPIs increases, “unit management” becomes increasingly tedious. This article summarizes how to solve this problem cleanly. ✔ When a KPI is selected → Automatic unit change ✔ In tables → Rows show %, Totals show currency ✔ With 1 column → Simultaneous expression of Weight + Total These are patterns you can apply immediately in...

When creating reports, we often face the same dilemma: "I want to see both Sales and Growth Rate—do I have to create two separate charts?" The feature that solves this inefficiency in one go is Field Parameters . In this article, we will cover everything from switching multiple KPIs in a single chart to applying dynamic formatting, all in a practical way you can use immediately. 1. What are Field Parameters? (Conceptual Understanding) When you utilize the Power BI Field Parameters feature in a chart, it allows the axis (X-axis) or values (Y-axis) to swap in real-time based on the selection a user makes in a slicer. • The Old Way: You had to create complex SWITCH function measures or overlap multiple charts using the 'Bookmark' feature. • The Current Way: Dynamic chart control is possible with just a few clicks, and maintenance is extremely easy. As a re...

In the professional world of Power BI, Dynamic Format Strings go beyond mere visual effects; they are a core technology that accelerates data interpretation. This is especially true when report users are executives who prefer intuitive units and symbols over complex, raw numbers. There are three primary core scenarios for dynamic formatting most frequently used in practice: ✔ Automatic Scaling based on Magnitude: Displaying 'Billion' for large values and 'Unit' for small values. ✔ Format Switching based on Selected KPI: Automatically changing formats (e.g., '$' for Sales and '%' for Growth Rate). ✔ Inserting Conditional Text and Symbols: Adding ▲/▼ symbols based on variance. In this article, we will focus on the setup methods and the automatic unit scaling among these three scenarios. 1. ...

1. What is SELECTEDMEASURE()? Simply put, it is a "placeholder" that refers to the "very measure currently being calculated." Normally, when writing DAX, you explicitly use the name of a measure, such as [Total Sales]. However, within Dynamic Format Strings or Calculation Groups, it is impossible to know in advance which measure will be used. In these cases, SELECTEDMEASURE() acts as a command that says, "Whichever measure comes in, fetch its value first!" • Usage: Dynamic Format Strings, Calculation Groups • Characteristics: Since you don’t need to hard-code measure names, the reusability of your code is maximized. 2. Why is SELECTEDMEASURE() a 'Revolution'? Suppose a company report has 50 different metrics, and you need to apply a rule to every single one of them: "If the value is 1 million or more, attach an 'M' unit; if it is 1,000 or more, attach a 'K' unit." ...

"When you first input data into a Power BI matrix, it appears in its ‘Default State’—without any formatting applied. Since the table options are set to system defaults, the lack of organization in lines, spacing, and colors often results in an awkward and unfinished look." In this article, we will pinpoint why matrices in their initial state look unrefined. We will then walk through a step-by-step transformation into a polished report by adjusting Borders , Row Padding , and Background Colors . 1. Why Power BI Matrices Lack a Bottom Border The default Power BI style, 'Default,' displays only the divider lines between data rows, while the Outer Border of the visual object is turned off by default. • Bottom of Column Headers: A line is inserted to distinguish between headers and data. • Between Data Rows: A faint line is inserted to separate individual rows. ...
