Graphing of downloaded data without the need for third party software Data accumulated in Normal mode Rolling mode and Histogram mode can be graphed using EL WIN s graphing module Data accumulated using One shot mode cannot be graphed in EL WIN this data must be processed using a spreadsheet See Chapter VII Part 2 It is theoretically possible for data accumulated in Normal mode Rolling mode and One shot mode to be converted into a histogram You will require a spreadsheet to do this Data accumulated in Histogram mode does not contain any time or date informa tion it can therefore not be converted either in EL WIN or in another software application into a Normal mode or Rolling mode graph a Viewing graphs To view an EasyLog datafile click on the Graph data button and select the datafile that you wish to graph If you gave the datafile an appropriate name during the download procedure then your file should be easy to identify Once you have clicked on OK your datafile will be graphed Click the maximise button in the top right hand corner to view the graph full screen You will notice instantly that the following information is automatically included on your graph i for data recorded in Normal mode and Rolling mode The EasyLog module s serial number is displayed in the top right hand corner The graph title up to 30 characters long can be displayed above the graph Alarm levels can be displayed2.
