best way to store data from a plot on hard drive

[Monse]

I have a DAQ set-up that will be on 24/7 for several days, and the whole time it's streaming data to an XY-Graph with a limited buffer.  My question is, what's the best way to store my plot data in such a way that I can empty out my plot every few hours but if I want to pull up data from a few hours ago I would just have an option on my initial VI to view any old saved plot data.

Basically, I'm trying to not overload my RAM with all my plot data so I'd like to save it to the hard drive while my VI is running, and only display, for example the last 8 hours worth of data... I've been looking at TDMS, but I'm not sure if that's the right solution.  

much thanks!

Hi,

You could save your data using TDMS as well as ASCII to simply load it in another application later.

Attached VI shows you how to save your data to a File after a certain amount of iterations, you can combine this then with your code and a timestamp.
