the forward and backward keys on the keyboard.
The coordinate values of the selected point will appear in the
information bar at the bottom of the graph window.
To display the second cursor: Double click again anywhere
on the graph area or click 2nd Cursor on the graph
toolbar.
The information bar will now display the difference between
the two coordinate values. If the x-axis is time 1/dt will also
be displayed.
To apply linear curve fit: Use the cursors to select a range on
the graph, then click Linear Fit on the main toolbar
To take a derivative of a plot: Use the cursors to select a range
on the graph, then click Derivative on the main toolbar
