Appending to data labels

Append values to your data labels.

Easily insert custom strings into the data label object using Overlays.

Using chart overlays

Use the array "overlays" to pass a list of objects for each corresponding data label. Each data label can have multiple overlays applied to it.

Overlays can require a 'value' (string), 'color' and where in relation to the data label the overlay needs to be positioned ('position').
