<p>The method involves detecting two supports (a1, a2) that are exerted on a touch control surface (5), and generating a rotation control of a graph e.g. two dimensional graph, about an axis of rotation (A), where the control is associated with the detected supports. The two supports are detected at the same time or in a preset lapse of time. The axis of rotation of the graph is determined according to position of the supports on the touch control surface, and according to pressure of the supports. The axis of rotation is perpendicular to alignment of the supports. An independent claim is also included for a control device for controlling rotation of the graph displayed on the display screen.</p> |
