I have a sine wave that I'm reading with a graph. This data is the acceleration reading from a specific material. I'd like to capture damping for this material...when I turn off the vibration switch, the damping cruve begins to degrade. I would like to "freeze" the graph at this point, manually, then capture the current data points that are on the graph in an excel file. I'm having trouble getting the data to line up with the curve I want to see on the graph. Is there a way to just capture the graph points that are currently displayed. I'd rather not use an image file

You could do this if you don't mind your DAQmx buffer filling up while it's frozen. In addition, you could add code to check whether freeze is changing value and start/stop acquisition accordingly. Or you could change your acquisition type to be On Demand instead of continuous.

Saving current graph data

Solved!

There are many ways to down-sample. You could average every other point together if you wanted.
