Introduction
In many of the solutions to the problems, waveform plots are used to find values of voltages, currents,
frequencies, etc. The values are found using the cursors activated by a left-click on the name of the trace
appearing above the plot. The cursor position is inserted in the plot by the command ‘Plot Settings →
Notes & Annotations → Label Curs. Pos.’ or keyboard shortcut ‘F4’. When inserted, the position is
given with a large number of digits, typically eight. In most cases, this does not correspond to a relevant
precision, so the position is edited to a reasonable number of digits by an editing of the text appearing in
the text window resulting from a right-click on the label with the cursor position.
