Drag a cursor to move it.

The cursor tracks the mouse until you release the mouse button, and then the cursor snaps to the nearest data point.

Actions by Offset Knob

You can operate on graph from the "Offset Knob" after pressed "Offset Knob" in the following ways :

Press the up or down arrow key to increase or decrease one record number (or corresponding to date ) in the graph .

Zooming and Panning on Graphs
