Hi I am unable to understand the output of the following function. 

ListPointPlot3D[Table[Sin[x^2 + y],
                      {x, 0, 3, 0.15}, {y, 0, 3, 0.15}],
                      AxesLabel -> {"X axis", "Y axis", "Z axis"}
               ]

enter image description here

I have told X and Y to be in the interval [0,3] But the diagram is showing an entirely different range for these variables from about [0,21].

How did this happen?

    You gave ListPointPlot3D a matrix of values. Each value of interpreted as a “height” (z-coordinate) and the matrix indices of the values as the x and y coordinates.

    Perhaps you want

    ListPointPlot3D[Join @@ Table[{x, y, Sin[x^2 + y]}, {x, 0, 3, 0.15}, {y, 0, 3, 0.15}]]

    Mathematica graphics

    or

    Plot3D[Sin[x^2 + y], {x, 0, 3}, {y, 0, 3}]

    Mathematica graphics

    Also take a look at the docs of the Mesh option of Plot3D.
