How to plot data in real time?

lm700 · November 2018

Hi,

I would like real time plotting the data that cyton board sends.

I tried real time plotting from the csv_collect file that allow to record the data on csv file. But I can't get a real time plotting, I get only snapshots.

How to resolve this issue? Is there another way to get a streaming data through python?

I've just started learning to code, so any help would be greatly appreciated.

Regards

LM, hi.

This is what the LabStreamingLayer is designed to do. Use OpenBCI_Python to create an LSL stream, then consume it with your other Python process code,

Hello,

Thank you for your reply.

But I do not understand how to do it.

To create an LSL stream, I have to use the plugin streamer_lsl which is on openbci_python ?

And when I have the LSL stream, how consume it with the python code that allow to plot data, how to make the link with the different codes ?

Does not already exist a code that allow plot data in real time with cyton board?

Is there a tutorial that describes all the steps to do?

Thank you in advance

The ExampleCode.wiki is basically a tutorial. The OpenBCI_Python page has a tutorial for starting the stream.

Below links are not LSL or Python related, but do allow various graphing options from Javascript,
