How I can save and display multiple measurement in same graph

The problem is that I can save data to file, but I want to make a history graph of measurement where is min, max and average voltages. How can I make this at the same time when I save to file my measurement. For example if I have 50 different measurements and I want to show them while I am measuring. I attached a picture of graph what I am meaning.

HVing multiple plots on the same graph is just a matter of building a 2D array (it can be done in other ways too though). Wire the different arrays representing each plot into a build array function. Search the examples that come with LabVIEW and you'll find sample code...

In LV7 there is an example showing different ways to feed plot data into a graph (Waveform Graph.vi).

Thanks Mads I try that. Maybe I can work out my problem with that way. And maybe I have some beginners luck.
