2nd Y axis?

Hi Schrodinger,

Nothing good on television, so I had another play with Numbers 3.0.1

The graph on the left is the Numbers magician's trick to mimic a second Y axis. If two Y axes are what your professor or journal editor or conference chairman require, then obey them. They are in charge. Maybe Numbers is not suitable to your task.

The graph on the right shows concentration of all three reactants over time. ClO and Br- decrease, and BrO and/or Cl- increase. Time (minutes) is a shared X axis and the graph has three Y variables, all to the same scale.

Note that I have changed the Data table to show *mmol* dm-3 so that the graphs show what I think of as sensible numbers (Scientific format makes my head spin). Again, follow instructions from your professor or journal editor if you are required to use *mol* dm-3 and ignore my changes.

In my humble opinion, the graph on the right shows the trends without your audience having to do mental arithmetic. All concentrations are to the same scale.

Regards,

Ian.

P.S. To superscript the "-" sign in a table heading, select the "-" sign, then Format Inspector > Text > Gear Wheel > Baseline shift

This does not carry over to the axes labels or legend on a graph. You must format them yourself.
