Create device comparison graphs in Digi Axess

Device comparison graphs show data collected from the automation applications configured for the devices. Each graph is an analytic input and shows processed data. The comparison graphs display in the Device Comparison page.

Graph represents one automation application configured on one or many devices

Each graph represents one automation application that collects and processes data configured on a device. The graph displays data from the device with a data line, which is labeled with the device name and represented by a unique line color. To ensure that data from more than one device is included in a graph, multiple devices should have an automation application configured with the same name, and should ideally collect the same type of data.

For example, you have 5 devices that collect air temperature data. Each device should be configured to have an automation application called Air Temperature, and that manipulates the air temperature data. When you view the device comparison graphs, you will see a graph called Air Temperature with five lines of data, one for each of the 5 devices.

Data intervals

The data is displayed in the following increments: current day, three days, one week, two weeks, or 30 days. Changing the increment in one graph changes the increment for all graphs. You can also zoom in on a particular section of a graph to see more detail.

Devices included in the graphs

By default, the comparison graphs include data from up to 10 devices that have data. Devices that have not collected data are ignored. If you have more than 10 devices that have collected data, the Select Devices to Compare page displays and you are required to select the devices that you want included in the graphs. You can select up to 10 devices.

You can change the devices that are included in the graphs as needed by clicking the Edit Device Selection button in the Device Comparison page.
