In Google Sheets it is possible for data labels in a chart to reflect the number formats for individual scale points? Even if its only possible via the Google Sheets REST API that would be fine.
Currently it is possible in a chart to set the number format for data labels to "From source data", and data labels in the chart do successfully reflect that format.
But my problem is that the chart reads the custom number format only from the first cell in the source data, and then applies it to every data label in the series. Example
In the image below, the chart successfully reads the custom number format from the first value...
But what I want to get is like the mockedup image below:
