Multiple ordinates with log y and linear scale at the same graph

Question

Is possible to make graph, with one linear ordinate on the left and different on the right but logarithmical?

In MWE below, there is my attempt, which is not working. I am getting these errors:

**C:\Program Files (x86)\MiKTeX 2.9\tex\latex\pgfplots\pgfplots.sty:227: Paragraph ended before \pgfflt@readlowlevelfloat was complete.

Please move the inner axis environment below \end{axis} and use alignment options (for example named nodes, see manual) to place it at the desired position.

Answer 1

You are missing \begin{tikzpicture}, have written y axis style instead of y axis line style, and have a typo on the third coordinate of the first plot: 9,.50 should be 9.50.
