Use Case

If the default gauge widget doesn't sufficiently cover the desired use case, a more advanced version is necessary. Additional customization has been setup for the process screen approach.


Process screens are advanced options. It will require some level of HTML, Javascript & CSS understanding.

  • Administrative access to the portal
  • Back-end access to the portal server, or coordination with delivery engineer to help place CSS & Script files.


Note: Originally designed for a dark background, edits may be needed to adjust to white background


  • Conditional formatting.
  • Multiple tags (3 max).
  • Exposed a large set of high charts variables for customization.
  • Real time & aggregate historical data calls

Samples shown below (dashboard export is attached, tag names will need to be set).


Process screens are a bazefield widget option available in dashboards. It provides a way for customers to build fully customization visualizations. Process Screens have description in the Dashboards user manual that can be found on the portal help section. Process screen manager can be found in the portal for UI upload & download access point.

Highcharts gauge examples can be found here. 

Steps (To Use)

Step 1: Ensure process screen, scripts & css is loaded up into Process View Screen Production folder.

Contact support or delivery engineer to ensure this is added appropriately.

Step 2: Add Process Screen widget to dashboard

Open the dashboard you want to add the widget to, click 'Add widget', then select Process Screen.

Reference the process screen name as 'Gauge' as shown below. Choose a height that makes sense for the widget location and desired size of the visualization.

Step 3: Setup Query Parameters

Note: Reference Variable List below for options

It is best practices to copy the query parameter string to a text editor of your choice. Shown here is notepad++.

Add new line characters (\n) to all & symbols to view the parameters better.

These parameters is an example configuration. The minimum parameters needed are at least 1 tag, i.e. tagName=${Site}-ActivePower.RT. 

Format goes as follows:

  • &: Additional parameter (Only needed after the first parameter
  • variable= : variable in the query variable column of the Variable List table.
  • &tagName=SITE-WTG01-WindSpeed

This is adding additional variables to the javascript url parameter list, this is a general html option. To read more about it, check out this wikipedia and look up javascript usage as well

After you have included all the desired variable definitions in the parameters string, copy and past it back into the Edit Widget 'Query parameters' section and close to apply.

Step 4: Test Setup and Adjust Parameters for desired effect.

An example simple option:

Here we see that the default location of the gauge ([50].[50]) in the pane center variable, needs adjusting. The top of the pane is trimmed off, so we should shift the centerY parameter. 

This looks better, however it isn't fitting the height of the process screen, which we set for 600.

Step 5: Troubleshooting

If the applied settings don't produce a visualization, there is most likely an error. Errors are visible in the Developer Tools or Source Inspector section of your browser. Using google chrome as the example (F12)

Showing below, we added a '%' symbol which will cause issues with URL query strings, as % will be used for symbol references.

Using the developer tools, you can take a dive into the source code and the failure location to help troubleshoot the location of the error.

Variable List

Note: Do not pass % characters in query string, for options that are in percent, the code will automatically format it with the appropriate percent
