Custom trends and graphs do not need to be created and configured in the Setup menu section. Their main purpose is to quickly analyze the processes, changing the set of parameters, shifting and scaling them for easy viewing.
They are accessed in Setup / Analyitcs menu.
This sub-menu will only be available if there is at least one register in the project with 'save data for graph' option set.
Then you can select any register from the project which have been enabled for logging, and set shift, multiplier and the vertical axis for the register's value.
Tip: The vertical scaling by default is set to 0..maximal value on the selected time interval. If the value becomes negative in some point the curve will be shrinked to 0 in this point. Don't forget to appropriately set min. marging for the vertical axis.
The navigation in the viewing area is the same as for graphs.
After you configured some set of data on the custom graph, you can save it as a static(pre-defined) graph. This feature is available since the 4.0.7161 fw number.
You will be redirected to the page for creation a new static graph with register list from the source custom graph.
The custom trends entry is the next to custom graphs in the Analytics menu and it is always available becuase any register can be immediately viewed on the trend in real-time mode. The custom trend setup is the same as for graphs with the only difference they have extra setting for the time interval viewport will be scaled to.
Starting from the 4.0.7161 fw number the custom trend can be saved as a static one, with the help of 'save' button. See the figure for the custom graph setup above.
Some data, like process or machine states (stopped, run, alert) with their duration can be conviniently presented on the Gantt diagrams, which are also available in Analytics menu (since fw 4.0.7161). The registers for the Gantt must have 'save to graph' property set.
The state is shown as being ON, or colorized, depening on the register values:
The legend below the diagram shows registers' title, id, total state ON duration on in the current diagram view.
Starting from 4.0.7164 there is a meters log analytic on the device, without data to Level2 upload.
Resource register's data can be represented in a custom analytics way, which are also available in Analytics menu (since fw 4.0.7164). The registers for this kind of analytics must have 'resource meter' property set.
Unlike level2 resource meters and consumption analysis, there is no comparison in monetary terms, to be able compare different types of resources.
