Have a look at "surface charts" But Excel is not very good for 3D plots.
The x and y axes are treated as categories as with x-axes in Line plots not
as real numbers as with XY plots. So to get a useful plot, the increments
for each axis must be constant. For example x can be 1, 1.5, 2, 2.5, 3 but
not 1, 1.5, 3, 4.
A true 3D plot is on my Excel wish list.
best wishes

I am interested in drawing the following graph:

A pipe profile which is defined by (x,y) say, (x1,y1), (x2,y2).....
Now for a particular value of (x,y) i want the the pressure to be ploted
along y axis.
The data input fpr pressure is like this

For (x1,y1) Pressure p1
(x2,y2) Pressure p2
