Recovering lost data

[mafaldamoreira]

For context, I was running a simple LabView routine to acquire data from a device in real time. Upon getting an error message, I accidently pressed "clear chart" on the output waveform graph. It appears this cleared all my data up to that point from the output file. Does anyone know if there any chance the previous data can be recovered from app cache or is it definitevely lost?

You cannot "clear a chart" when you have a waveform graph…

Clearing a chart (or graph?) cannot "clear data from the output file" - because a chart/graph is only an indicator (aka data sink) and an "output file" should also be just a data sink. (THINK DATAFLOW!)

How can we suggest anything about your VI when we don't know your VI?

• How do you save data to the output file?
• How is the chart/graph "connected" with your output file?
• How do you handle your measurement data inside your VI?

Usually when you clear data inside your VI before it gets saved to a file then the data is lost…

For even more context you should attach that simple routine…
