A Spacer row can be used to space waveforms apart, and as a place for showing arrows and labels.
- Select to show or hide the row's name with "Show name".
- A set of row name options include a choice of font, font color, font background color, and text alignment (horizontal and vertical) relative to the waveform region in that row.
Initial values for the set of row name options,
come from the Waveform options dialog (Diagram | Waveform options).
If you check the "Use default options" box above a set of options, those options will be affected by any change made to them in the Waveform options dialog. This allows you to define the looks of multiple rows across the entire diagram. Otherwise, uncheck the box to individually customize each of those options.
