Choose Store Latest Run from the Experiment menu to save the most recently collected data. This allows you to collect additional data without losing a previous run.
The run labeled Latest always contains the most recently collected data and is overwritten when you collect more data. When you store the Latest run a new data set named Run 1, Run 2, etc. is created and the values of the Latest Data Set are moved to it. Columns in the latest data set are drawn with bold lines on the graph, while other columns are drawn with thin lines.
You can set Logger Pro preferences to Automatically Store Runs, which will automatically save the Latest data before each data collection is started.
Note: Choosing Store Latest Run does not save data to the file, nor will it preserve your data between sessions or when you turn off your computer. You must choose Save from the File menu to save your data.
