Retrieving decompress data (raw data without compression)

    I wanted to see if there is a a way or API call that can be used to retrieve the Decompressed data. To my understanding the data saved in the archives is stored after a compression algorihm is applied to data. We want to use the raw data without compression is there a way to pull that?

Note:Values stored in the archive of PI Data Archive undergo a compression algorithm that removes all values that represent the same slope. Values stored in the PI Data Archive snapshot have not undergone this compression algorithm. If you specify the current time in the time period of the Compressed Data function, the function retrieves a snapshot value for that time. That snapshot value might not be subsequently stored in the archive due to compression.
