Saving Analysis Data
Option 1. via the ARN
If your data is stored in an ARN (located in the Analysis Results folder) of the Tree, then you can simply right-click and select Save Data to File...
Option 2. via the chart window
You can also save the data from the chart window by selecting Save Data to Text File... from the right-click menu.
Note, however that due to historical reasons these two file formats are different to each other.
