Acquire 4 channels of temperature data and then graph it on the same graph.

Check the examples that ship with LabVIEW.

Mike..

PS: before you do that, though, you should go through the online free tutorials.

Assuming your measurements are coming at some regular interval (once a minute or once a second, say), you can use a Chart to plot the four channels as the data evolve (just as though it were a strip-chart recorder, though you could also make it "sweep" as through it were an oscilloscope beam).  The Help on Charts (and on other LabVIEW functions -- select one on the Block Diagram and type Ctrl-H) will explain how to plot multiple channels.
