Can't Plot Multiple Values

[gallaugher]

CircuitPython Version

Am I doing something wrong? This code seems to run fine when I don't show the plotter at code.circuitpython.org, but the browser freezes when I show the plotter:
import board, digitalio, adafruit_lis3dh, busio, time

# Set up accelerometer
i2c = busio.I2C(board.ACCELEROMETER_SCL, board.ACCELEROMETER_SDA)
int1 = digitalio.DigitalInOut(board.ACCELEROMETER_INTERRUPT)
accelerometer = adafruit_lis3dh.LIS3DH_I2C(i2c, address=0x19, int1=int1)
accelerometer.range = adafruit_lis3dh.RANGE_8_G
print("Running Accelerometer Code")

while True:
    # Read, then plot the three axes x, y, z
    x, y, z = accelerometer.acceleration
    print((x, y, z)) # note the double parentheses!
    time.sleep(0.1)


Maybe it's freezing when I try to plot multiple values? It seems to, for example, print((x)).

I don't have that sensor to test, but I'm thinking one of two things is going awry: a) you needn't 'break out' the variables if you're only interested in direct read values (i.e., try simply
result = accelerometer.acceleration
print(result) ;
or b) the variables need to be parsed separately (e.g.,
value for value in ...
as per below).

Will it run successfully if you amend your print thus:

x, y, z = (value / adafruit_lis3dh.STANDARD_GRAVITY for value in lis3dh.acceleration)
print(f"x = {x:.3f} G, y = {y:.3f} G, z = {z:.3f} G") ?

I think I noticed something like this before. I'll have to dig in more and figure out why it's not working.

I tried this script and it was working for me:

import time

values = [1, 2, 3]

while True:
    print(tuple(values))
    values[0] += 1
    values[1] += 1
    values[2] += 1
    time.sleep(0.1)

Want to give it a try?
