The waveform supports the following functions:
• Tooltips with ON/OFF Measurements: Placing the mouse over a point in the waveform displays tooltips with corresponding ON/OFF voltage measurements (
Figure 14-11).
• Show Legend: Select this check box to show or hide the graph legend. You can also click one or more check boxes in the graph legend to hide or show the selected graph element.
• Stroke Thickness: Click the up/down arrows to adjust the thickness of the graph line. You can also type a value in this field to adjust the thickness.
