Data Labels in PowerPoint are used to display the value, and/or the name of the Chart Series, and/or Categories right within or above the Series on the chart. In versions older than PowerPoint 2013, Data Labels were contained within a plain text box. However, PowerPoint 2013 includes the new Data Callout option, that allows you to add Data Labels. This places your Data Labels within a specific callout shape.
