| Variance | Weight coefficient (accuracy 0.1) | Smoothed data line |

Traditional criterion (1/5) | Relatively centered numerical value | a = 0.2, b = 0.2, c = 0.2 | Non-smooth, canâ€™t keep peaks well, smoothing faster |

Local-midpoint criterion | Relatively small numerical value | a = 0.3, b = 0.2, c = 0.15 | Smoother, better noise reduction, smoothing speed in general |

Local-mean criterion | Relatively minimum numerical value | a = 0.3, b = 0.2, c = 0.15 | Smoother, better noise reduction, smoothing speed in general |

Global-mean criterion | Relatively large numerical value | a = 0.4, b = 0.1, c = 0.2 | Non-smooth, can retain peaks, and the degree of noise reduction is generally |
