c03efe4878
Previously, changing to a different scope was done by clicking the scope type button and cycling through all scopes. This commit decreases the number of clicks needed to switch between two scopes by adding a radio selector. The radio buttons can be shown or hidden by pressing the scope type button. This commit also makes the raw histogram one of the scope types.
