How to plot data vs. time from the saved .txt files
Posting on behalf of a user who is looking for a python script that plots the sensor data(Y-axis) over time (timestamp)(x-axis from a txt file.
I combed the Forum for relevant posts, linked ** below:**

is there a simple way to obtain a plot of Time series data, essentially?

Shirley, thanks.
Many search results also show up on this,

Do note that with Cyton, the sample values will have a DC offset component. The normal way to remove this is using a DSP library function that is a high pass filter at about .5 Hz. Python has many DSP library choices available.
thank you very much William, I'll bring this to the attention of the customer.
This explains the DC offset,
