How to change the x-axis of the Room Ac. Parameters plot type when plotting octave band parameters

As default the x-axis displays the octave band values, but it is possible to change the axis labels and gridlines. Below it is explained how to change the axis to a ordinary logarithmic axis.

Click on axis in the Room Ac. Parameters plot type. It will display the dialog box shown below. Click on the Axis tag, then the Labels tag. Then at the axis list at left select Bottom Axis.
