Use Time Navigation to stream past data across pins and heatmaps

00:03

Time Navigation in Tandem allows you to view past data in an easy-to-read view,

00:08

which can provide a better understanding of facility performance over time.

00:13

You can select a specific day or time period, and then use Play mode to stream data across pins, heatmaps, and charts.

00:22

To begin, open a facility in Tandem.

00:26

From the footer navigation, select Data Visualization.

00:31

Enable Stream Pins, then place your pointer over this option to expand a list of available stream pin statuses.

00:40

In this example, Alert, Warning, Offline, and Normal are all enabled.

00:46

From the Data Visualization menu, you can also enable Heatmap for future uses.

00:54

In the viewer, the pins display as colored circles,

00:58

and you can place your pointer over each to view a summary of the data being received by the associated IoT device.

01:06

In the top corner of the viewer, you see the timeline,

01:10

with the selected date and time and an option to view live data.

01:14

You can also expand the timeline to access the player bar and video scrubber,

01:20

as well as additional time navigation controls.

01:24

In this example, open the Date Picker, select a different date, and then click Apply.

01:31

Next, click different times on the player bar.

01:35

Notice that the Chart view updates as well, and the respective video scrubbers always coincide.

01:43

You can also select a custom time frame.

01:46

Expand the Custom drop-down, select Custom, and then specify the date range.

01:53

When you click Apply, again, both the player bar and the Charts update.

01:59

In this case, move the video scrubber back to the beginning,

02:03

and then click Play to progress through the date range in the viewer.

02:08

To stay in play mode on repeat, you can click Loop, and you can use the Change speed drop-down to designate the speed of play.

02:17

During play mode in this example, notice that the colors of the pins for the IoT devices change.

02:24

These indicate changing statuses, such as alarms or warnings,

02:29

and are based on thresholds that were previously set.

02:33

You can also stream data across heatmaps that were enabled previously from the Data Visualization menu.

02:41

To set this up, first make sure the view is set the way you need it.

02:46

In this case, a top view of Level 1 is selected.

02:51

Next, expand the Select heatmap drop-town.

02:56

Select the parameter that you want to view, such as Humidity or Airflow.

03:01

To change the visualization for Airflow, click Settings, then select a predefined Color Theme.

03:09

When you are finished, click the Settings icon again to close the Settings.

03:15

To make more room, collapse the Filters panel.

03:20

Then, click Disable filters so that all available data is included.

03:27

Expand the grid view.

03:30

Now you are ready to view the time-lapse of the facility data.

03:35

On the timeline, click to move the video scrubber to the desired starting point, and then click Play.

03:42

The heatmap displays the various changes for the selected variable, and the stream pins also show changes.

03:50

This can help you understand how the IoT devices are affected, in this case, by the airflow.

03:57

As it plays through time, you can switch back and forth to review the data in the Grid view or in the Chart view.

04:06

Use the Time Navigation feature in Tandem to better visualize your facility data across pins, heatmaps, and charts over time.
