Hi,
Documentation is publicly available here: https://zoomcharts.com/en/documentation/
In your case, it would be custom JS code that would be part of the dataFunction request which would process your specific data format and use replaceSettings({series:new_series}) to replace the data. This is the logic that should be used.
If you would like to have a functional example, I recommend getting a paid support and we could create a specific code for you.
Thanks,
Janis
