X axis on Graph??

[misschanda via OfficeKB.com]

Hello
I am doing a line chart and have gotten stomp. I have looked through of
couple of threads and wasn't able to figure out problem.

I have data, and would like to show this data graphically using two x axis
and one Y axis, being constant for the graph.
The first x axis would represent time that would be continuous.
The second x asix would represent temperature. The temperature plateau and
eventually goes back to zero.
Is there a way to make a graph to show the two x-axis sharing the y-axis???

Thanks
LA

You need an XY chart, not a line chart.
When you've done that, change one series to a secondary axis and it will
initially be using a secondary Y axis. You can then change it to use a
secondary X axis but primary Y axis.
