You need to remember most ppl are not able to reproduce your setup. You need to describe what your pde does. First question: Are you getting your data? As suggested by @erwrow, you can send the data in the same stream. Check this recent post to see the concept: [[SOLVED] ArrayIndexOutOfBoundsException: 1 - #4 by racs](https://discourse.processing.org/t/arrayindexoutofboundsexception-1/2288/4) and follow the discussion there.

> [Two sensors trigger same part of code - Processing 2.x and 3.x Forum](https://forum.processing.org/two/discussion/21447/two-sensors-trigger-same-part-of-code#latest)

After you get this part ready, then you can check this post to have an idea for plotting data: [real time graph plotting using processing - Processing 2.x and 3.x Forum](https://forum.processing.org/two/discussion/comment/100623/#Comment_100623)

Also check this as it displays one way to do it and it focus in the concept: [Sine Wave / Examples / Processing.org](https://processing.org/examples/sinewave.html)

Last, you can indent your code in the PDE before you post it here. To indent, select your code in the PDE and press `ctrl+t`. It makes your code easier to read after you paste it and format it here.
