What can you use to highlight trends in Power BI reports?

Using conditional formatting in Power BI reports is effective for highlighting trends because it allows you to apply visual changes to data points based on their values. This means you can modify aspects such as color, font style, or style of the data representation dynamically, depending on the underlying data conditions. For example, you may set a rule to change the color of data points to red if they fall below a certain threshold, thereby clearly indicating areas of concern or those needing attention. This immediate visual feedback helps users quickly grasp trends and patterns over time by emphasizing critical values directly in the report visuals.

The other choices, while useful in their own ways, do not serve the same purpose in highlighting trends. Formatting options provide a way to enhance the overall appearance of reports but do not apply dynamic changes based on data conditions. Static text boxes are fixed and cannot change based on data trends, and external images do not contribute to data-driven insights within the report. Therefore, conditional formatting stands out as the optimal choice for emphasizing trends effectively.
