The types of acoustical parameters that may be computed and displayed are shown below.

The parameters are explained in the documentation for the menu item Room Acoustics->Parameter Settings....

When plotting a single value parameter (e.g. STI), the x-axis is linear. When plotting a multiple value parameter (e.g. T30), the x-axis is set to logarithmic. As default the x-axis displays the octave band values, but it is possible to change the axis labels and gridlines, see the FAQ: Room Acoustics section of the help file on how to do this.
