By navigating into an entity (Accounts, Leads...) it`s not possible to pin a default chart into a view (the chart only appears when clicking on the "show chart" button and selecting the needed chart). The idea is to implement a feature with the ability to pin a default chart to a view which will stay always pinned/open (avoiding to click on the "show chart" button each time) when opening this entity and view.
