Time Series Overview

The WillowTwin™ platform empowers users to make proactive, data-led decisions in real-time to reduce expenses, grow profits and better manage risk; a major component of the platform that allows users to do this is Time Series.

From here, users can view trend data for assets, twins and items loaded into their digital twin, and enables them to identify areas of concern and opportunities to remedy potential issues by comparing and analyzing data from your twin or portfolio over time.

Time Series data is made up from the Internet of Things (IoT) and Operational Technology (OT) data sources that are connected to your digital twin. This is not limited to, but can include:

  • HVAC
  • Energy & utilities
  • People & occupancy
  • Vertical transport
  • Air quality

Because many of these data sources collect information at different rates, Time Series aggregates it and displays the average, minimum, maximum and count values for the data points in a graph for users to evaluate and determine what steps they may need to take next.

Navigating to Time Series

The Time Series feature can be accessed from a few places within your WillowTwin™ platform, the main menu and from insights. 

From the main menu:

  1. Click the menu button menu_button.PNG
  2. Click Time Series

From Insights (if already on the Dashboard):

  1. Click on an insight from the main Dashboard OR click the Insights tab, then click on any Open or Acknowledged insight
  2. Scroll to the bottom of the insight, a small time series snap shot may be displayed if there is data available from the asset the insight was generated from
  3. Click the Go to Time Series button to access the full feature


Not all insights will always display time series data, this will depend on the asset and/or how the insight was created.


Viewing Time Series Data

Selecting Assets

When accessing Time Series for the first time, users will be prompted to search for and select the asset(s) they wish to see data from. An Asset Finder window will open on the right side of the screen where users can search or browse to specific assets from one or more buildings in your portfolio.

To Find an asset: Asset_finder_3.PNG

  1. In the Site field, select the site you are searching for the asset from
  2. In the Search field, enter the name for the asset
    1. Note: if no floor or category has been selected, the search will be finding from all assets in the building. Selecting a floor or category will search the assets in just the selected floor or category
  3. From the Floor drop-down, select the floor the asset is located on
  4. In the Category field, select the category of asset
  5. The asset(s) that match your search criteria will be displayed below, click the Add button to the right of each asset that you wish to add to your Time Series graph
  6. Click Done

Working with Time Series Graphs

Once one or more assets have been added, users will be able to identify what specific data points they would like to view on the map, as well as set date and time periods for viewing the data. The main interface can be broken down in to 3 sections:

  1. Asset panel
  2. Menu bar
  3. Graph view


Asset Panel

The asset panel is where users will be able to see the selected asset(s), enable or disable data points to view on the graph, as well as add or remove assets from the Time Series view. To enable data points to appear as a graph to the right: TS_data_1.png

  1. Click the triangle to the left of the asset name to expand and view the data point options that are available
  2. Click the eyeball icon beside each data point
    1. A colored eyeball indicates the data point is enabled and will be color-coded with the graphical representation to the right
    2. A grey eyeball icon with a strike through it indicates the data point is disabled

Menu bar

The menu bar options just above the Time Series graphs allows users to choose a data period for how much data should be displayed, as well as save the data/graph view as a favorite that can be recalled at a later time, recall saved favorites or download this time series data into an Excel spreadsheet.

To change the date period:

  • Click one of the preset date options
    • 24H, 48H, 7D, This Month, Prev. Month, 1M, or 3M
  • Click the date selector drop-down to select a custom date range


To Save your view as a favorite:

  • Click Save Favorite
    • In the Name field, enter a name for the view
    • In the Group field, select either My Favorites or Site Favorites
      • My Favorites - will only be seen by the user who saved the view
      • Site Favorites - -will be seen by all users with visibility to the site
    • Click Save Favorite


To recall a saved view:

  • Click the Favorites button
    • In the window that opens, click the Load button to the right of each of the saved view names
      • Views will be saved and listed under either the My Favorites list or Site Favorites
  • Views can be removed as well, while viewing the list of saved views, click the 3 dots on the far right of the view names, then click Remove from favorites

To download Time Series data to an Excel spreadsheet:

  • Click the download button  download_button.PNG on the far right side of the Time Series menu bar

Graph View

The data users will see in Time Series will be displayed as line graphs, depending on how the view is configured, this could display one or more graphs that can be used to identify how a piece of equipment has been operating over time, comparing the operation of the same or similar pieces of equipment from different locations within a building or from a different site, and much more.

TS_graph_data_points_2.PNG As mentioned earlier, each graph will be color-coded with the enabled data point(s), the vertical axis on the left will display the unit(s) of data being reported, while the horizontal axis at the top will display the date/time period the user specified.

Hovering over the graph will display the individual data reported by the sensor for a given day and time, moving the mouse left or right along the graph will display the information for each data point reported.

This graphical view can be very useful in identifying true gaps in data, but also note that because the data from different pieces of equipment is reported at different time intervals, some graphs may appear as dots with no connecting line in the graph. If this occurs, users can change the time interval in the top right of the graph view to display information from a longer or shorter interval.


Users can also adjust the display of the graphs to either group, stack or display each graph separately, depending on how they wish to analyze the data. Click the graph stack options button in the top right corner of the graph panel to adjust, options here include:

  • Twin
    • This will display the data grouped by asset (twin)
  • Grouped
    • This will display like-data overlaid with each other, in the example pictured below, you will see all air flow sensor data enabled for each asset will be overlaid on one graph, whereas zone air temp sensor data enabled for each asset will be overlaid on another graph
  • Stacked
    • Will display each graph separately, stacked one on top of the other in the order they were enabled
  • Shared
    • Will overlay each graph over top of each other in a single graph


Depending on the level of detail that is displayed in a graph, users can also zoom in on any section by left clicking and dragging over the segment of graph they wish to zoom in on. Again, depending on the time interval set in the top right corner, zooming in may result in the graph appearing as a series of unconnected dots, if this occurs, adjust the time interval as needed.

To zoom out, users can click the Reset button that will appear near the top left corner of the graph view.
