Plotting the Velocity Data

[yoga79]

Hi all..

I am a beginner in C++ programming, and i want to learn about C++ seriously..
I want to ask about a case..
I have velocity data of fluid flow:
Positions (three colums)--> X Y Z, and
velocity field (three colums)--> Vx Vy Vz.
I want to plot this data in 2D and 3D graphs. Would you mind to help me for make the code of this data...??
Thanks for your help and your attention ^_^
