Current versus historical data
The data shown in a trend can come from two sources. For current values, data comes
from the value table as it is collected. The value table is a record of the most recent values
collected from the data source, and is stored in temporary memory while the application is
running.
For historical values, data comes from a data log model’s log file, if a model is assigned to
the trend. You can show both current and historical data in the same trend.
For information about data log models, see Chapter 26.
Time, date, and number formats
The trend is shown using the time, date, and number formats of the current application
language. For example, if the application language uses a comma for the decimal symbol,
the scale on the y-axis uses commas for the decimal symbol.
