impulse response graph in %

[linuxonly]

in rew 5.31.3, how do you switch the impulse response graph y-axis from dbFS to %?

From the help file:

The REW Impulse graph displays the impulse response. It shows the values as either % FS or dBFS. The dB scale is useful to see a wider dynamic range of the signal, rather than plot the values directly it plots the base 10 log of the values multiplied by 20. The top of the dB plot is 0 dBFS, which corresponds to 100% FS

Never mind. Just figured out a dropbox appears when you hover where you should do.
