| Data displaying logics |
|
1.If the selected time range is within the original data storage duration (two days by default), the original data is displayed. 2.If the selected time range is beyond the original data storage duration (two days by default) and is within the hourly data storage duration (five weeks by default), the hourly data is displayed. 3.If the selected time range is beyond the hourly data storage duration and is within the daily data storage duration (12 months by default), the daily data is displayed. (For example, suppose all data storage durations use the default settings. When you view the data of this week on Tuesday, the time range is within two days, so the original data is displayed for the data of this week. When you view the data of this week on Wednesday, Monday of this week is beyond two days but the time range is within five weeks, so the hourly data is displayed for the data of this week.) |
