Picking position
To navigate through the graph using the mouse pointer, choose Pick Position in the main menu to set new origins 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.
The absolute position of the virtual window can be changed by choosing Position in the main menu. In the message window the user is prompted for the x and y coordinate. This is followed by the upper left corner of the virtual window and the upper left corner of the display window being moved to these absolute coordinates.
There are several ways to find out about the values of absolute coordinates:
- Turn on the ruler
- Invoke the Statistics item of the Information submenu to get information about the maximum size of the virtual window (Maximum x coordinate and Maximum y coordinate)
- Invoke Node Attributes in the Information submenu to find out about the absolute positions of nodes (see layout attributes)
- When using the scrollbars of the virtual window the absolute coordinates are shown in the message window
It should be noted that this positioning mode can be left only by entering the two required coordinates.
