This feature is a tool for inserting either native or custom data labels to the selected chart. Native data labels is default, and is used by the majority of cases, while custom data labels will be inserted at the same location as the native ones, but the user can add or edit text as needed.

It opens a dialog in which the user is able to define the range of labels and select which series the labels should be applied to. Further, the user can select the type of the label. There are two options for how the labels are to be inserted: 1) basically using the native functionality to insert the data labels with the application presets of the category name and values, and 2) we create an unattached text box that allows the user to have a longer description text into the data label that is assigned to each chart item.

If the chart is a pie or doughnut chart, the user has further options for the number format of the data label.
