I'm currently building a javascript map visualization in an analysis. When a user clicks on a point on the map, I want it to change another analysis in a dashboard.
How can I use the javascript I've placed in a narrative within an existing analysis to change the surrounding analyses on the same dashboard? I.e., when a user clicks on a point in the JS generated map on NY, NY, I want to change the chart to the right of the map (another analysis) to only include data about NY, NY.
I assume this means that the JS code would need to change a session/presentation variable in OBIEE that could then be used to change the other analyses.
From within a narrative, using Javascript, how can I change a session or presentation variable for a dashboard?
