Using Tentative Points
Tentative points let you see where the next data point will be placed before you are committed. They also let you define a data point relative to the tentative point. You can specify the distance from the tentative point using a key-in or, better still, using AccuDraw and its input window. The exact location of tentative points on elements are determined by the current Snap Mode, or snap override setting.
You can enter tentative snap points manually, or you can turn on AccuSnap and let it display tentative points interactively as you move the pointer over elements in a view. With AccuSnap active, when the Tentative Point marker displays, you can enter a data point to accept it. Even when AccuSnap is active, you can enter a tentative snap point manually, by pressing the Tentative button on your system's graphical input device.
Tentative Points Working with Multi-Snaps
When Tentative Point snap encounters a multi-snap mode, it evaluates each snap mode in order, building up a list of candidate snaps for the current target element. Each successive tentative point snap steps to the next candidate snap. When the end of the list of candidate snaps for the current target element is reached, the next target element is picked and a new list of candidate snaps is created, and so on.
