# Graph Sample Rates

The information presented in the graphs on the Statistics page is based on continuous samples taken every 5 seconds over a 24 hour period (sampling does not occur during pauses or disconnects).

The data is displayed in either 60 or 120 columns (depending on the time span being displayed), where each column represents an average value based on the time span being displayed.

Graph Time Span | # of Columns (Data Points) Displayed |
---|---|

Last 5 minutes | 60 |

Last 60 minutes | 60 |

Last 24 hours | 120 |

For example, if the graph is showing data from the last 5 minutes (300 seconds), then it will contain 300 ÷ 5 sec. = 60 samples over 60 columns (this works out nicely to one sample per column).

If the graph is showing data from the last 24 hours (86400 seconds), then it will contain 86400 ÷ 5 sec. = 17280 samples over 120 columns. Each column contains the average value of 144 samples (17280 ÷ 120).
