Data retrieval options

You can control how data is retrieved within your view by adjusting the sampling interval or organizing the data based on an attribute as a key column.

• In an asset view, data is retrieved in one of the following ways:

  • Evenly spaced in time (also known as interpolated)

  • Based on a reference attribute time (also known as compressed)

  • Time stamps are taken from the reference attribute; depending on the option you choose, all others are either interpolated or given a null value if there is no value for that attribute at the exact timestamp.

• In an event view, data is aligned by event frames and is formatted in one of the following ways:

  • One summary record for each event. This is ideal for Pareto charts.

  • A Pareto chart shows both bars and a line. Individual values are represented by bars, with longest bars on the left. The running total is represented by the line.

    

  • Evenly spaced or based on a key column in time within event frames. This is useful for golden batch analysis.
