ipdsCompactInterval
| A compact data storage type for fixed-interval data sets that uses 4 bytes per
data point.
The first and second data point x-values added to the channel determine the fixed-interval used for the entire data set. For example, if the first data point's X-Value is 1, and the second data point's X-Value is 6, then the X-Value interval between all data points in this channel will be fixed at 5 (Interval = 6 - 1 = 5). All future X-Values will be ignored. This was done to keep backward compatibility with previous log files and data sets. This data set does not support the following features...

ipdsFullFeature
| A large data storage type for data sets that intend to utilize the following
extended features….
Individual Trace Line Styles, Color, and Width Individual Data Marker BrushColor, BrushStyle, PenColor, PenStyle, PenWidth, and Size properties. This Data Type will always support all extended features of the channel object as we add them to future versions Note: this Data Style should not be used with extremely large data sets due to the larger amount of memory storage needed for each data point. If you must keep your memory usage low and you don't plan on using extended features of the channel, then we recommend not using this Data Style unless necessary. | 100 bytes
