Hi folks,
I'm looking for a way to set the '2733' in my command below equal to the amount of datapoints available.
[data, time] = thingSpeakRead(readChannelID, 'Field', fieldID1, 'NumPoints', 2733, 'ReadKey', readAPIKey);
For context, I'm trying to setup visualisations that still work when the dataset in the channel is changed. For my current dataset, I have 2733 lines so the above works, but I'd like to get it to the point where it can work without amendment when I change the dataset.

See this documentation. The NumPoints can be at max 8000. If you have less than 8000 points in your channel, everything is returned. If you have >8000 points, only the most recent 8000 are returned.
I'd recommend also answering this survey from the developers as they are looking to provide functionality based on use cases.
