It appears that the v1 API GetTrendDataForParameter function returns AVG trend data (data from the Dataavg table), is this correct? Is there a way to data from RT table?
Thanks
GetTrendDataForParameter will return real time trend data in case the parameter is only real time trended and not average trended (see the trend template). If there is average trend data for the specified parameter, then this method will return the average trend data.
There's another web method, GetTrendDataForTableParameterV2, where you can specify if you want real time trending or average. This method can be used for any parameter (it doesn't have to be a table parameter). If you request real time trend data, while the parameter is not real time trended, then it will return average trend data in case that is available for the specified parameter.
