Hi Drizvi,

As Chris mentioned in this forum post , there are a number of different possible 3-D graphs that you can work with in LabVIEW. The 3D Contour Plot.vi example found in the Example Finder (Help>>Find Examples>>Browse>>Building User Interfaces>>Displaying Data>>Graphs and Charts) may be the best example for you to build off for you application.

In the future, please make sure to keep each of your questions limited to a single Discussion Forum thread.
