Unlike the Trend object, the Data Analysis object can display pens belonging to different Data Loggers at the same time. The name of the Database which each Data Analysis pen belongs to can be specified in its "Data Logger Name" property. If this property is not specified for each individual pen, the Data Logger set in the Data Analysis style property will be used instead. If a Data Logger cannot be found at runtime due to a programming error or error in the datalogger name for instance, an error message like the one below will be reported in the Historical Log and in the output window's "DBMS tab:
Cannot link to 'VAR00001' pen inside 'DataAnalysisName' trend to the 'DataLoggerName' Data Logger!
When a Data Analysis displays pens deriving from different Data Loggers, the recording points of each pen will be placed along the X axis according to the time they were recorded. If the Data Loggers differ in recording times, the Data Analysis will display each curve with the corresponding different number of points for the interval time selected.
In this situation the point by point scroll buttons, "First Point", "Last Point", "Previous Point" and "Next Point", can be used to scroll the different points of the pen selected in the legend. If a pen has not been selected in the legend, the points of the first pen on the list will be scrolled instead when using these buttons.
