We will use pgfplots for a three-dimensional plot of an exponential function.

We will apply a style for reduced and shifted axes, to get a distraction-free visualization.

If you don’t have it already, download the file http://pgfplots.net/media/tikzlibrarypgfplots.shift.code.tex, and put it into your document folder.

Load this style in your preamble by:

\usepgfplotslibrary{shift}

Now, we can use the shift style, as in this short example.

The code, and more, is explained in the LaTeX Cookbook, Chapter 10, Advanced Mathematics, Plotting in three dimensions.
