analyzing past data in real-time

[Perfluorine]

Hello,

I use LabView to measure the frequency of the semiconductor sample versus time. My current code graphs the signal in real time as I run the experiment + it writes data in the file. Now my goal is to determine the slope of my first graph and plot it versus time. Thus in order to find my slope I need to use past data points together with the current data point. Can anybody please suggest the easiest way of how to get those points and use them in further calculations?

I am posting my code below.

Thanks.

Please take a look at this post and see if it is what you are looking for.  Otherwise, try storing your data in arrays and then doing the calculations with the arrays.
