ETC Graph?

[samboralot]

Hi there, first time poster.
Loving REW for my new studio setup, however I cant find the ETC graph as mentioned in the brilliant 'how to use REW pt2' video on youtube. Has this feature been removed or moved somewhere? The tab doesn't exist in the current version

Many thanks

ETC is on the Impulse graph.
