Time Series Explorer

This guide will help you familiarize with the Time Series Explorer to gain insights from data.

Introduction

The Time Series Explorer is a tool designed to enable users to quickly analyze and gain insights from measurement data or events associated with specific tags. It allows users to compare multiple tags, view historical trends, and monitor real-time data streams without requiring any special programming skills.

Key Features

1. Asset Hierarchy selection & Tag Navigation:

   • Select an Asset Hierarchy to explore data from.

   • Navigate through your tags using either the hierarchical structure of assets or using list view, to find the tags you need.

2. Tag Selection and Filters:

   • Search and filter assets using the input box to locate specific tags quickly.

   • Hide undeployed nodes to focus only on active data sources.

   • Double click any Tag to add its associated measurements to the time series graphs.

3. Historical and Real-Time Data Views:

   • Toggle between Historical and Realtime views to analyze past data or monitor ongoing measurements.

   • The timeline slider lets you select custom date ranges for precise analysis of historical trends.

4. Visualization Options:

   • View line graphs that show data trends for selected tags eg. avg, min, max or standard deviation.

   • Easily compare multiple tags by adding them from the tag navigation view.

   • Adjust resolution for a more granular or aggregated view of data.

5. Stream Playback:

   • Enable the live data stream for real-time monitoring of tag measurements.

   • Pause or resume playback using the controls available next to each tag.

Asset Hierarchy selection & Tag Navigation

The Asset Hierarchy Selector in the top lets you select an Asset Hierarchy to explore. Only Asset Hierarchies, that have been deployed to a device can be selected.

• The Asset Hierarchy selector also lets you filter between deployed hierarches using text when expanding it, if you have many Asset Hierarchies to choose from.

• The Refresh button refreshes the Time Series Explorer available Asset Hierarchies and clears any Tag selection or data already loaded into the page.

• The Live data stream icon in the toolbar indicates whether the Time Series Explorer is currently connected to an Edge device (Its only connected if a Real-time data stream is started).

Once an Asset Hierarchy has been selected and loaded, all the Tags of the hierarchy will be shown either in in the Hierarchical view or List view.

Hierarchical view

The Hierarchical view shows the selected Asset Hierarchy using a hierarchical structure in its latest deployed version.

• The input text field in the top, lets you search the hierarchy for any node or tag that matches the input text.

• The hide undeployed nodes switch, enables you to hide any Asset Node or Tag that is not currently deployed. By default all Nodes and Tags are shown, but their names are greyed out in the asset hierarchy tree, to indicate they are currently not deployed.

List view

The List view shows only the Tags that has been deployed from the selected Asset Hierarchy, leaving out the contextual information you would get from using the Hierarchical view. A list of Tags is shown as an alphabetically sorted list on the hierarchical name of the Tag.

• The input text box in the Top, lets you filter the list of Tags to only show nodes containing the text entered into the text field.

• The hide undeployed nodes switch, enables you to hide any Tag that is not currently deployed. By default all Nodes and Tags are shown, but their names are greyed out in the list, to indicate they are currently not deployed.

Adding Tags to Time Series

Regardless of whether you are navigating tags through the Hierarchical or List view, you can easily access a context menu by either right-clicking on a tag or clicking the icon that appears when hovering your mouse over a Tag. This menu provides the following options:

• Add to timeseries: Adds the selected Tag to the Tag list located at bottom of Historical - and Real-time Data View and loads measurements or events into the graphs.

• Remove from timeseries: Removes the selected Tag from the Tag list, removing any graph that might be visualized for the Tag.

• View Asset Model: Will navigate to the Asset Designer and select the owning Asset Hierarchy.

• View Device: Will navigate to Monitoring and select the Device where the Tag is currently deployed.

• View Deployment: Navigates to Deployments and selects the deployment that was responsible for this Tag to be available on a device.

When tags are added to the Tag list at the bottom of the graphs, the Time Series Explorer automatically retrieves measurements for the selected tags. It then renders graphs based on the Tag type, whether it is Analog, Digital, or String, ensuring that the data is appropriately visualized for effective analysis.

The Tag list has the following columns:

• Tag Icon: An icon that indicates whether the Tag type is Analog, String or Digital (As shown above).

• Graph Color: Shows the chosen color for the visualization of the Tag in the graphs. The color can be changed at any time, by simply clicking the colored box.

• Name: Tag name identifier.

• Stream: The button lets you Play/Stop real-time data stream from the Tag. When Play is toggled, the Time Series Explorer will automatically navigate to the Real-time view.

• Action: Removes the selected Tag from the Tag list, removing any graph that might be visualized for the Tag.

• Tag: The ISA95 hierarchical name of the Tag.
