[vtkusers] How to create XYZ plot?

[董理]

Hi all,

What is the most convenient way to do this job? My data is two dimensional,
say f(nx,ny), and the coordinate values along each axes, say x(nx) and
y(ny)respectively. I tried to use
*vtkRectilinearGrid dataset to interfacing my data into VTK. I set x and y
coordinates to vtkRectilinearGrid, and a virtual z coordinate, but what
about f? How can I add it into the dataset?*

**Thank you for help!

Best regards,

DONG Li
