Starting with object generation 2.56 all mouse operations require that you simultaneously press the Ctrl-key.

An alternative technique to zoom is to click with the mouse (left button) somewhere in the graph: the position of the mouse cursor is the center of the newly created view. Both the new x-and y-axis have half the range of the previous setting.

Clicking with the right mouse button also selects the mouse cursor position as the new center but now both axis ranges are doubled.

With lots of left and right mouse clicks you can move – again after the investment of a certain training time – very quickly through the data.

If you click a graph with the left mouse button outside the x- and the y-axis the plot parameter dialog (see below) pops up. Also for this action you must press the Ctrl-key as well.
