Which of the following are examples of conditional formatting in Power BI? Select all that apply.

The correct choice encompasses the concept of conditional formatting, which refers to the dynamic alteration of visual properties based on the data being presented. In Power BI, conditional formatting allows users to enhance data interpretation through visual cues.

Customizing the color of bars in a bar chart based on predefined thresholds is a quintessential example of conditional formatting. By setting thresholds, you can automatically change the appearance of bars to indicate different data ranges, making the visualization more intuitive. For instance, a bar might turn red if it exceeds a certain value, signaling a potential issue or highlighting an area of concern.

While other options may involve changing appearance based on data, they don't specifically align with the typical use case of conditional formatting in Power BI. Options that involve changing sizes and colors without specific data conditions or maintaining a uniform appearance through static styles of text do not fall under the conditional formatting umbrella as clearly as the correct choice.
