some scalar
data.And coordinates like following:
file1:
    x1 y1 z1
    x2 y2 z2
        .
        .
        .
        .
    xn  yn zn
file2:
    x21 y21 z21
    x22 y22 z22
          .
          .
          .
    x2n y2n z2n
.
.
.
filen:
        .....
but I could not find a way in document to do this.(every file have different
number of
points).
Could anybody help me in right way?
