Hi,
I am trying to display datalabels (ex: 'N/A') for null values in bar and column charts, but it does not seem to be possible. The API has a reference to nullFormat and nullFormatter for datalabels, but it does not seem to be possible. Old workarounds found on Google do not seem to work anymore neither.
Here's my non-working example:

Any idea how to achieve this?
