I am quite new to the Vega world inside Kibana and would like to make a Vega visualization interactive so that the Kibana filters are updated on click.
I have seen the following tutorial --> [Update Timefilter from Vega]((Vega - Tutorial: Updating Kibana filters from Vega - 《Kibana v7.9 Guide》 - 书栈网 · BookStack)
The challenge now is that I don't want to filter on the Time field, but on other fields and don't know how to address them in the Signals. In the tutorial, I understand that the time is set/filtered with the "SetTimeFilter" function in the following code snippet.
I took the code from the tutorial and adapted it analogously for my data. The graphic is clickable but the update in the signals fails obviously because I do not pass any date.
So the question is which kind of other functions are available and how can I update/filter for my Keyword-Field "News".
