Question: TrnGetPeriod returns the sample period that is being displayed not the real trend sample period. There is no way to find out what the actual sampling period is for a trend. This means that there is no way to calculate how many samples will be requested for a specific time interval. How can I get the trend sample period? 

A new function called TrnInfo() has been provided to get this information. This function has been provided in version 3.00 and later.
