Let's say I have a Kibana Dashboard. The dashboard shows a bar plot. I embed the dashboard as an iframe into a parent application. The user clicks a category in the bar plot. I want the parent frame to respond in some way.
Is there a way to accomplish this? Does Kibana issue any calls to postMessage() that I could intercept to determine when certain events occur within the dashboard? Do any plugins exist that implement this functionality?
I see certain references to postMessage() when I inspect the Kibana dashboard, but it appears this may be limited to an underlying library using web workers. I don't see any documentation surrounding the subject, but I want to know if this functionality is possible, even if only through hacks or plugins.
