CHOPs channel as overlay

Hi,
I recently started to use TouchDesigner and did some basic tutorials :wink: . Right now, Im doing one from Matthew Regan (great tutorials by the way). In his tutorial he used some basic CHOPs to do audio analytics, ā€œsplittingā€ the audio file with different audio filter CHOPs and then combine and display this spectrums in a merge CHOP. Now iā€™m just curious: in his video the merge display shows the channels ā€œon topā€ and in my project, the merge is displayed as 3 seperate channels (i attached a screenshot).
Is this some kind of display option? I checked all the parameters but was not able to find it.

Oh dear, just one secound later i found the solution:
viewer to active > number of graphs > all channels in a single graph
:unamused:

And more generally, you can change the global default in the Preferences Dialog under the CHOP page of preferences.
