Power BI Event Viewer

Event Viewer

The Event Viewer chart visualizes device events over time. Ideal for IoT devices that report new states

Example

See here for an example if the embedded version is not working.

Data Fields

The Event Viewer chart needs data it a specific way.

• Devices - Field that contain the different devices that have state changes.
• Time - Time values used for the time axis.
• Event/State - The state value/string reported by the device(s). This field will be aggregated using the 'First' aggregation.

Important

The visual aggregates events per device and timestamp; by sure that the datasets contains a maximum of one event per timestamp per device. E.g. if there are multiple events per second, the visual will only visualize one event and the rest of the events is ignored.

• Colors - JSON Array with prefix link colors: [{name, color}]: use to set the different state colors to the provided one.

Unknown

With the unknown formatting option it is possible to alter the 'unknown' state. The unknown state can be used is the first event of a device is arriving late compared to the start time of the axis.

• On - Turn the unnown state on or off
