Great !
If your project is to create a fixed-size oscilloscope abstraction, may 
be it's a good idea  to check also  the original discussion and patch  
by Ingox


(https://forum.pdpatchrepo.info/topic/11184/colarray-a-graphical-array-where-color-and-line-width-can-be-set)

 , as my work was mainly  to embed it with some extra features (dynamic 
patching, properties gui, state saving, mobmuplat export) that make 
complexity grow.

thanks jean-yves,

thats some serious wizzardry and it seems that i could build my 
oscilliscope from that :-)
have to study it a bit more to really understand, whats going on under 
the hood.


in the meantime i built sth with purr data, which has a properties 
dialogue with a colorpicker. for arrays.

(i wanted sth simple + workable quickly).
ultimately i think, that would be good to have in pd as well.

also will check out your mob collection, as i am a big fan of 
mobmuplat, which sadly seems dormant but still keeps working on the 
newest iOS.

There is some trickery to get an array name with $0 tag, but it's

thank you, roman and alexandre, for the pointers!

it seems, the best option is to wait, till the discussion alexandre 
referenced (https://github.com/pure-data/pure-data/pull/711) comes 
to fruition.
purr data has implemented such a color picker for arrays, so that 
would be the second best option.
i looked into Jmmmp multiarray, but i seemed to be better suited at 
displaying static waveforms.

maybe i overlooked something.

i am (ab)using pd as an eight channel oszilloscope.
things get messy pretty fast without colors.

As someone mentioned in one of the other threads, you could achieve
colored array displays with data structures.

An example is here:

Probably much closer to what you actually need is the [multiarray] from
the jmmmp library. It's in Deken.

Out of the blue, it would be possible to do it in gem. That might be the
best way.

Re: [PD] is there a way to color the points/curve in an array?

[hans w. koch]

thanks joao,

i looked into multiarray which of course is great,
just for my purpose of creating an oscilloscope, where updating at audiorate is 
crucial, it didn´t seem to be the right candidate.
your answer about limiting data refresh rate seems to confirm my (admittedly 
quick) asessment.

i am trying to kind of model the mordax data eurorack module 
(https://www.mordax.net/products/data) with 8 channels.

start Pd with "-d 1" to see the core->gui  messages, with "-d 2" for gui->core 
(or was it the other way round?) and OR the values to see the messages in both 
directions.

Is It possible to know exactly the messages that are sent to PD by the GUI
