82. At Adventure Works, you’re tasked with understanding the rise and fall of sales data. The company uses Microsoft Power BI, a tool rich with functionalities that can aid in data visualization and analysis. As a data analyst, you’re particularly intrigued by the features of cross-filtering and cross-highlighting. Which of the following statements are true about cross-filtering and cross-highlighting in Power BI? Select all that apply.

Cross-filtering allows a selection in one visual to filter out unrelated data in another visual. (CORRECT)
Cross-highlighting is used to display raw data directly.
Cross-highlighting dims or fades unrelated data but still displays them. (CORRECT)
Cross-filtering is the default behavior for most visuals in Power BI.

Exactly! The cross-filtering feature in Power BI is powerful because it allows for dynamic interaction between visuals. When you select a data point in one visual, it automatically filters out unrelated data from the other visuals, helping you focus on the relevant subset of data for a more precise analysis. This interactivity enables a more detailed and intuitive exploration of the data as you move through different elements of your report.

Meanwhile, cross-highlighting serves a slightly different purpose by dimming or fading the unrelated data points in the other visuals while keeping them visible. This allows you to maintain context and still see the broader picture, all while emphasizing the specific data point you’re focusing on. Cross-highlighting provides a more subtle way to hone in on key insights without losing track of the overall trends or comparisons across the dataset.
