WORKING WITH HISTORY DATA AND FILES
By default, the history file is named history.dat and is located in the ~\My
Documents\HeavyWeather\History\directory. This directory is where the Heavy Weather Pro application looks for history files to display in the History tab of the File Management window.
If you choose to save your history file to another location, it is recommended that you either set the History directory to that location, or copy your history file(s) to the default directory so that they can be used when working with templates and graphs.
VIEWING HISTORY DATA RECORDS
We can view history records from the current history data file, or from previously saved history data files.
If you are viewing the Current Weather window, you can simply click the Data link in the lower left corner to see the history data records stored in the current history file.
To view the data records stored in a previously saved history file, you must first select and open a template file.
With a template file open in the main window, select the Data link in the lower left corner. 
Note: If you have not selected a template in the main window, the Data window will only display history records from the current history file.
In the File Management window, select the History tab. Select a history file. To display the data records in the selected history file, double click the filename or click the checkmark at the top of the History tab.
The Data window will display the data records for the selected history file.
