Franz,

Just use the PlotRange option. (Mathematica has a built-in algorithm for
trying to plot the 'most interesting' part of a function. It does not always
choose well.)

Plot3D[
    Exp[-10*(x*x + y*y)], {x, -1, 1}, {y, -1, 1},
    PlotRange -> All];

In some cases you may want to specify explicit plot ranges.

Hi there,

I just want to plot the very simple exp-function:
Plot3D[Exp[-10*(x*x + y*y)], {x, -1, 1}, {y, -1, 1}]

But the resulting plot is cut off at z(x,y)=0.2! So the result is simply not
an exponential!

I'd appreciate any help,

Franz
