Picking Position
To navigate through the graph using the mouse pointer, choose
Pick Position in the Position menu of
the menu line or press the p key.
The Pick Position operation works in two modes:
- New origins can be selected continuously by repeated short
left-clicking at any position in the graph window. With each click the
upper left corner of the graph window moves
to the position clicked on in the virtual window. This
operation continues until the right mouse button is pressed.
It is only of limited use for the
normal view,
however it is especially helpful for
fish-eye view.
In fish-eye view the Pick Position
operation sets the new focus. The entire graph is
drawn in self-adaptable fish-eye view, consequently this operation
enables the entire graph to be easily browsed through by moving the
focus over any points of interest.
- When the left mouse button is pressed and held, followed by
dragging over
the graph window, a rubber band appears. This not only causes the origin
to be set but also a scaling to be calculated so that just the area
inside the rubber band is magnified to fit in the graph window.
