Subject: Passing Filter Parameters When Creating a Sankey Diagram Using an API Data Source in Helical Insight

Snipaste_2026-07-28_16-16-20

Hello Helical Insight Team,

I am currently using Helical Insight 6.2 and trying to create a Sankey diagram using an API as the data source. The format of the data returned by my API is shown in the attached image.

In my current use case, I need to display different Sankey diagrams based on selected filter conditions. For example, I would like to use department, energy medium, and a time range as filter conditions, pass the selected values to the backend, and dynamically generate the Sankey diagram based on the data returned by the backend.

How can I pass the selected filter values from Helical Insight to the backend API?

Thank you.
