read last 2000 historical points for a tag

[unclebump]

I can make the read historical trend read the first 2000 points by just wiring the constant to the number of points terminal or when I wire only the start timestamp value and the constant. If I only wire the stop timestamp value and the number of points terminal it still reads the beginning 2000 datapoints. Is there any method to read the last 2000 historical points, or do you have to read all historical data and index the last 2000 points??? I just didn't want to waste time reading data that I did not want to see.

Currently, National Instruments does not have a reverse reader implemented in the Citadel interface. However, for me, your use case sounds really usable and therefore, I hope someone at National Instruments will take this idea and implement it in the future.

The workaround looks kind of ugly to index the latest values by providing a trial-and-error start and stop time window.

Hope this helps
