Final answer:
It is false that changes to data labels must be made using the Format Data Labels task pane; there are several ways to edit data labels in a chart.
Step-by-step explanation:
The statement suggesting that you must make changes to the content of data labels using buttons in the Format Data Labels task pane is false. While the Format Data Labels task pane provides a range of options for customizing data labels in a chart, you are not required to use these buttons to make changes. There are usually multiple ways to modify data labels, such as directly selecting and editing them in the chart itself, or using right-click context menus. The Format Data Labels pane does offer a convenient and detailed set of formatting options though, and is often the preferred method for making more complex adjustments to data labels.
