1. A roll map of an electrode coating process, comprising:
a roll map bar that is displayed on a screen in synchronization with movement of an electrode between an unwinder and a rewinder while being coated with an electrode slurry in a roll-to-roll state, the roll map bar being displayed in a form of a bar by simulating the electrode in the roll-to-roll state; and
a representation part configured to visually show at least one of quality-related and defect-related acquired data associated with the electrode coating process, the acquired data being shown on the representation part at a certain location on the roll map bar corresponding to a location in the electrode at which the data is measured.
