iFIX stores parameters for historical queries with the chart rather than with the Historian data source itself. When a data source is imported in a symbol file, and then loaded into a chart, the item configuration for the symbol's data source will be the default item configuration, and therefore it may not match that of the pen in the chart.
If this is the case, you will receive warnings in the import log stating that the default information has been used.
To correct this, in the Proficy Portal display, open the symbol file and configure the data source accordingly. For more information on how to do this, see the Symbols and iHistorian Data Sources topics in the Proficy Portal online help.
