LabVIEW
How can I plot data from a large .lvm file (Memory Full)?
Looks like you need at least a few hundred MB in ram, which could easily explode if your code is inefficient and creates unecessary data copies in memory.
What is the structure of the file? As a first step you might avoid dynamica data. Maybe you can read it in a more direct fashion using lower level file IO. Also avoid local variables as well as trying to graph the entire set at once. I assume none of this is needed for your offline processing.

I did read all the data using the read from text file vi and displayed it all in a strinbg indicator (reading in x number of bytes/lines at a time)... How can I no plot this text/string data?
8GB won't really help you unless you also use LabVIEW 64bit. 2GB should be OK.
To graph it, you need to decimate it as shown in the link I gave you earlier. Most likely, your monitor has only a few thousand pixels across, so it is not worth to display more points than that. It won't look any different if done right!
Can you show us your code? Can you attach a small sample file that has the same structure, just with less data?
An array indicator also uses a lot of memory. As a first verification step, just look at the array size, for example.
