Target Bar in Vue Bullet Chart component

The line marker that runs perpendicular to the orientation of the graph is known as the Comparative Measure and is used as a target marker to compare against the Feature Measure value. This is also called as Target Bar of the bullet chart. Also, if you want to display the target bar you should map the targetField name from the dataSource.
