I´m trying to overlay two different plots. Each of these plots has different y-axis units but they share the same x-axis.
For example, plot-A is logCO2 x % and plot-B is logCO2 x pH.
So I would like to overlay these two plots and have a graphic plot that I could see the logCO2 on the x-axis and % in the y-axis on the left side of the plot, and pH on the y-axis on the right side of the plot.
Is it possible?
