save plotted chart graph as data

[parker555]

hi there,

I've got this program that collects data from an amplifier.  I left it running for a while and got a figure out of it. but when time came to stop the program running, I clicked on the "stop run" icon on labview program and not the button I created to stop-the-program-and-save-data. 

So, my question is that data plotted on the graph saved somewhere that I can access it? or is it impossible to save?

cheers

Hi parker555,

can you attach your vi? To use the LabView stop button to exit your prgram is a bad solution.

Hi P

have you opened the vi again?
Does it show any relevant data on the graph?

If so is it relevant?, then either make default or copy graph FP to new vi and make data default.

Stopping an execution via the stop run button icon is not recommended.
I would say actually all data is lost.
If you were controlling a system all states would be un known!This is extremely hazardous in the real world. Also instruments could cause damage.

If you have built you application methodically and included return to stable state ( power supplies switched off etc) then then program stop button achieves all this.

thanks all for your replies.  I blame my novice level of LV programming for this...I'll try and digitise the image and extract the graph from the image

cheers

Do you still have the VI open with the graph and the data still in it?

Try making a copy of the graph.  Then go to the block diagram and turn the graph into a control or a constant.  You should be able to create a small program to extract the data out of that.

If you've closed the VI, then the data will be lost.
