parametric graphs

Hi all,
This may sound a silly question, but...
I have some data that measures the relationship between
temperature and viscosity of various chemicals. Since this
relationship varies over time, I'd like to add a third
axis (time the measurements are taken).
Is there a way of creating 3axes'd graphs on excel without
using add-ons?
Cheers

Excel cannot deal with charts that have 3 numerical axes.

I've found that two axes are usually sufficient for presentation of this
kind of data, since it's hard to interpret x, y, and z values when the
chart is shown in perspective view. I would make multiple curves of
X=Temperature and Y=Viscosity, with one curve at each measurement time
(or alternatively, switch temperature and time).

Andy Pope has a simulated 3D scatter chart on his web site
(http://andypope.info). If you need a solution outside of Excel, you
might try products like SigmaPlot or DeltaGraph.

If your independent variable values are all equidistant, you can create
a 3D surface plot. See the Excel/Charts/3D Surface page of my web site.
