Provides a standard Windows dialog box for the selection of a data log file (*.log).  Currently, only flow rate data log files will be processed and graphed, other IFT2000 *.log files or non-IFT2000 *.log files will not be graphed, and will present an error message to the user.

No other File/... options will be available until a data file has been successfully opened.

Once the data file has been opened, the flow rate data will be presented graphically on the display with a default (and minimum) Time axis of 10 minutes, and a default Flow axis which is based on the average flow rate as determined from the last average flow rate reported in the data file.  The Flow axis default is called 'Average Flow, Centered, Fitted', which indicates that the average flow value will be centered on the Y-axis as best as possible, and the maximum and minimum scale values will be dependant on 'fitting' the worst case flow values on the graph.

Along with the actual graph, the following data is also presented on the screen: Maximum flow data value, Minimum flow data value, Set Rate, Total Time of the test data in the file (minutes) and the Number of Points in the data file.
