I created a dashboard with several different widgets. They do update when I add filters to the layers. However, when I click on a point (school) all that happens is that the point is highlighted. When I right click, I can "show pop up" and other things. What I want to do is for the widgets to update when I click on any one point.
You are going to want to configure your widget's properties, and under Data Source, chose your layer with Selection.
That should enable your widgets to work off the selected features.
