Hi, every one!  
I am a beginner to Paraview.  
Could someone help me to visualize the data please?  
I have vti files where 2D velocity data also in.

This is the vti file  
Uploading: vtk003885.vti…

I can 't draw 2D streamlines with mask points

I want to draw a two-dimensional streamline like this one.

Try with the Evenly Spaced Streamlines 2D tool.
