To trace function select function and click the button trace function  or select menu item <Analysis><Trace Function>.

This will cause the Trace dialog box show. On page Trace simple scroll the data or function and follow the cursor to trace values and derivatives. You can change cursor on page Visualize. On page Analyse it is possible to find zeroes and extrema of the function and to pick peaks of datasets.
