how do I plot a data series against two series

[Guest]

I want to plot one data series against two axes. I can get the secondary axes
and I can get it onto the x axes at the top. What I want is to get the second
axes to be dependent on the first. You see the second axes is the volume
fraction of a composite ply and the first is the weight fraction. I want to
create a graph so that the data series I plot can be looked up by either the
volume fraction or the weight fraction. The problem is that the volume
fraction axes scale needs to be irregular since it's a nonlinear function of
the weight fraction. Firstly, I'd like to know if that's possible.

If so,
HOW DO I DO IT?

Please tell us how the data is set out.

Assuming I understood you, it is possible to simulate the effect. See the
link 'Singe chart with dual axis' at http://www.tushar-mehta.com/excel/tips/

That method is fine for a situation where the two measuring axes are linearly
related to eachother like celsius and fareinheight. (9/5 +32 ) but my
situation has the two measuring axes being in a non-linear relationship to
eachother ( Vf= (Wfration fibre/density fibre)/(Weight fraction fibre/density
fibre+Weight fraction matrix/density matrix)
So I can't just scale the axes by changing the min and max of the axis.

So what I need to do is have one of the x-axes regularly spaced and the
other irregularly spaced so that they are equally far from the y axis when
they are equivalent.

From what I've seen so far from other posts and the excel help, it looks as
though this is not possible.

Thanks anyway.

they are equivalent.

It is always possible to simulate an axis. But, you have to provide more
information about the nature of the two axes. Clearly, if you are plotting
one data set against two metrics, there has to be a relationship between the
two measuring systems.

OK. It's your call.

One of your axes has to be made independent of Excel's axis capability.
Since you know how VF and WF interrelate, this is not a major problem. This
page shows how to make an arbitrary axis scale, and gives links to some
examples:

I responded before noticing Tushar's contributions to the thread. In any
case, it's certainly possible to get what the OP asked. Whether the two
parameters are related linearly is irrelevant.

Here's the link I provided in my other post.

It's certainly possible. Gut feel says you're going to need to use a
dummy series to simulate the secondary Y axis rather than use a built
in secondary axis. www.peltiertech.com has examples of using dummy
series as axes.
