5.10.4 Zooming

It is possible to zoom in to an area of the graph by selecting a rectangular zoom area with the mouse. Left click on the Graph window to define the first corner of the rectangular zoom area and while pressing the left button drag the mouse pointer to the opposite corner of the zoom area. In order to zoom out right click on the Graph window and the last zoom will be undone. If you have zoomed in several times and you want to zoom out completely you either have to repeat zooming out several times by right clicking on the Graph window or you can press the Reset Zoom button in the Toolbar or select the Graph Reset Zoom command in the View menu. The Reset Zoom button is gray when no zoom is active.

Another way to use zooming is to go to the View menu and to select Graph Zoom...This will open the Graph Zoom dialog (see figure Graph Zoom dialog) where you can specify a zoom area based on timestamps (x-axis) and function values (y-axis). You also have to specify the Graph window where the zoom has to be applied to.
