In the case when for a selected plot scale 1 minute or more will fit into 1 pixel of the screen, then the average values (5) of the register and the zone (4) of the range of values for estimating the distribution of the minimum and maximum peaks will be displayed on the graph. This averaging is drawn using cached data from the database, corresponding to the current scale of the view (in the database, averaging is stored for 1, 2, 5, 15 and 60 minutes). This method allows you to optimize the work with graphs when viewing large amounts of data on a different scale, while maintaining the speed of work. | In the case when for a selected plot scale 1 minute or more will fit into 1 pixel of the screen, then the average values (5) of the register and the zone (4) of the range of values for estimating the distribution of the minimum and maximum peaks will be displayed on the graph.

For the big amount of monitoring data, it is recommended to take care of data redundancy and use a special server which fetches log data via the API to the DB or the Level2 cloud server option. | ||
