How do I save my data in LabChart?

To save data as a LabChart (.adicht) file, simply click File >> Save as. Name the file appropriately. You will have the option to save the data, or to save just the settings of the file. 
LabChart can also save data in other formats (several varieties of text, MATLAB, IGOR, WAV, PCLAMP, Binary, EDF, csv). For these options, follow File>>Export... Name the file appropriately, and select the Save as type: as desired.
