The Universal Containers Einstein Analytics team built a dashboard with two widgets: 1: List widget associated to the step “Type_2” and grouped by the dimension “Type” (multi-selection) 2: Pie chart widget associated to the step “Step_pie_3” and grouped by the dimension “Type” The team wants to use bindings so any selection in the List widget will filter the Pie chart. Additional notes: * The steps use different datasets. * Users should be able to choose more than one Type (multi-selection). What is the right syntax for the binding?
