Hi Ive,

This is possible with some limitations:

• Between 2 trend graphs with parameters:
  You can link the 'Timespans' of one chart to the filter data of another. This will make the linked chart update its viewport whenever the first one changes.
  • The second chart cannot be zoomed out manually in this way, because it only knows the current timespan of the first chart.
  • Linking the second chart back to the first will cause the same behavior as above, but for both charts.
  • The second chart will no longer be in sync after certain manual interactions.
• Between 1 trend graph with parameters and one with a query:
  You can link the 'Timespans' of the parameter chart to a filter node in the query to only fetch the results inside the current viewport.
  • The other way around/2-way linking is not possible.
• Between 2 trend graphs with queries:
  This is not possible because these charts do not expose information about their current viewport.

Feel free to get in touch if something is unclear.
