Selection Zoom

Selection Zoom allows you to zoom in on a given portion of the graph. To use Selection Zoom press and hold the left mouse button on the graph where you would like the corner of your selection to start. Then drag the mouse until the rectangle surrounds the area on which you would like to zoom in.

If you would rather have a square instead of a rectangle, hold down SHIFT while dragging the mouse.

Once you let go of the left mouse button, the graph will zoom in on the selected area.
