Appearence of lines from buffer

hi,
I would like to visualize some datas with curves thanks to buffer.

Is this possible to write the curve as soon as the index is written ?

I can’t make anything else than replace former buffer data.

here’s what I have:

And here’s what I want:

you could just move a black quad over the part you don’t want to see…?

thanks ton film.
it could be yes :-)
but there’s a little glitch at the moving quad border…
is it possible to improve this ?

please take some time to understand what i added to the patch and how it works. its really not complicated and you only have to adjust the value of one pin a tiny bit.

Or you can use Current frame of the Ringbuffer to get just the values before the current frame.
