Could the choices for the Value Mode in the Tag Historical setup be renamed to better reflect what the user is choosing? The options of 'Discrete' and 'Analog' are poor descriptors for what is being selected. Better choices would be something along the lines of 'Raw Data (no compression)' and 'Analog Compression Algorithm'.

To almost all control engineers, 'Discrete' means a boolean (1 or 0) and 'Analog' means an integer or real value.
