If I follow, you want the normal x-axis and two vertical y-axes, the
secondary y-axis on the right of your chart.

Rt-click your second series and Select Object (or double click the series),
select the 'Axis' tab and select the Secondary Axis option.

Hello, i have 3 columns and i want to have the normal y and x axis,
but on the other side of the plot
i'd like to have also a z axis.
For example i want to plot a curve that is a function of x: y=f(x) and
Z=g(x) on the same plot and have y on one side and z on the other
side.

Thanks, contact me also via email
