Regional contribution — Stacked column chart; Publish chart in app — Select the chart for the table in app designer; Initial dataset — Set the Default View; Prevent chart switching — Clear Display Chart Selection

A stacked column chart is appropriate because each regional column can display the sales-stage segments that compose the region’s total pipeline, making both overall magnitude and stage contribution visible. A standard column chart would compare separate values but would not show composition in the same bar, while a pie chart does not compare multiple regional totals effectively. The chart must be selected for the Opportunities table in the app designer so it becomes part of the model-driven app package available to users. The dashboard component’s Default View should be set to My Open Opportunities so that dataset loads initially. To prevent runtime chart switching, Display Chart Selection must be cleared; otherwise users can choose another available chart. “Default Chart” determines which chart opens first but does not prevent selection of others. The maker should verify that the chosen view and chart are shared through the app and that users have privileges to the underlying opportunity records. The Study Guide explicitly covers “create and configure model-driven app charts and dashboards.” These four settings govern visualization type, app inclusion, initial data context, and runtime choice independently.
