Please see attached simple VI. What help I need is –
Update this VI such that for every run the Graph is saved automatically to a specified folder.
you have simply place write xls file function into loop & give a path to it then you can write data into file.
Use the File IO functions to set a definite folder path. Input the file name every time the VI runs and save the data to the file.
If you want to save the numerical data, use either binary/text file as per your requirement.
If you want to save the image of the graph, use 'Export image' in the invoke node for the graph control.
