I need to add anotations on channel data and then have it displayed in a graph. e.g. I have a photobioreactor from which i am measuring the Co2 level. Periodically i add fertiliser, or change ph or change the algae strain - at this time i need to add an annotation or tags so that this "event" is recorded in the data itself.
how can i accomplish this ?

Hi Vinod, thanks for the revert - but this is not quite what i am looking for. I dont want to explictly code, but want to be able to insert a label or annotation in the channel data via an API call , which is then picked up for during graph generation for data export.

The MATLAB visualization is generated by code, so, it makes natural sense to have the code generate the annotations as well. Currently there is no way to annotate the chart via just an API call.
