Hi, thanks for your help ... Unfortunately, that doc doesn't quite answer my question. I've followed the guidelines on how to create my own data source using those docs, but what I'm looking for is how to avoid using 'setresponse' to parse the returned data - we have multiple data sources drawing multiple graphs, and if they all make call backs to the same function, I can't differentiate the results.
The docs in your link tell me I can create my own handler in the 'response format' section, but what I'd like is an example bit of code to show me how - for example, how do I parse the returned JSON data and turn into a data object I can pass to a graph? It's quite possible I'm doing this all wrong, but for the life of me, I can't see a different way of doing it. Thanks again for your help, Tony.
