i want to make a like this movie...  who can help me..?

What's the question??

You can plot a 3D graph in LabVIEW like in the video. So take some wires, plug them in to your skin, acquire some data, and voila.

i can't use well labview.

my limit...

how do i change this vi? 

i am going to put in the voltage source  and check the resistance's voltage change.

1. using DAQ

2. my divice shape is square.

3. if i strain my divice, it's side resistance will change.

4. 3d graph show the divice's changed shape ... real time.

sorry i can't speak well english...

1st advice:

do not try to program everything at once. First you should program the data acquisition part of your application in LabVIEW. Test it, and write some data to a text file or 2D indicator. If these values make sense, then you can try to use LabVIEW to plot the 3D surface.

What kind of hardware you use? How many channels, acquisition rate? How do you represent a surface matrix? N X N matrix with N^2 voltage values, so you need N^2 channels? Or you use a kind of multiplexer?

2nd advice:

Start to go through the LabVIEW learning material, see top right part of the forum website... (self-paced learning, Core1-2, etc...)

A followup to Blokk's response (which I copied from another response by Sam Sharp):

Here are some useful links to some free training materials, taken from this page:

Doing a complex 3D plot from acquired data is not a good "first project" for LabVIEW (or any other programming environment).  You need to learn to walk before running a marathon.
