Strange data in IMU

Official Hardware Nano Family Nano 33 IoT

Hello,

I'm trying to get the IMU data with example code for the LSM6DS3

But when I analyse the data, I found some strange data as shown in image below.

/*
  Arduino LSM6DS3 - Simple Accelerometer

  This example reads the acceleration values from the LSM6DS3
  sensor and continuously prints them to the Serial Monitor
  or Serial Plotter.

  The circuit:
  - Arduino Uno WiFi Rev 2 or Arduino Nano 33 IoT

  This example code is in the public domain.

#include <Arduino_LSM6DS3.h>

long count = 0;
long start_time = 0;
long end_time = 0;
long hz = 0;

void setup() {
  Serial.begin(115200);
  while (!Serial);

  if (!IMU.begin()) {
    Serial.println("Failed to initialize IMU!");

    while (1);
  }

  Serial.print("start");

}

void loop() {
  float x, y, z;
  float gx, gy, gz;

  if (IMU.accelerationAvailable()&&IMU.gyroscopeAvailable()) {
    IMU.readAcceleration(x, y, z);
    IMU.readGyroscope(gx, gy, gz);
    
    Serial.print(count);
    Serial.print(", acc, ");
    Serial.print(x * 9.80665, 4);
    Serial.print(", ");
    Serial.print(y * 9.80665, 4);
    Serial.print(", ");
    Serial.print(z * 9.80665, 4);
    Serial.print(", gyro, ");
    Serial.print(gx * 0.01745329, 4);
    Serial.print(", ");
    Serial.print(gy * 0.01745329, 4);
    Serial.print(", ");
    Serial.println(gz * 0.01745329, 4);

  }
  count++;
  delay(3);
}

Is there anyone can explain what happened? Thank you so much.
