Previous pageReturn to chapter overviewNext page

The WANALYZER_VERTICAL_LINE structure (defined as WANALYZER_VERTICAL_LINE_DLL when used for COM interoperability) describes settings applied to a vertical line added to the Waveform Analyzer through the WaveformAnalyzer.GraphicItemVerticalLineAdd method. The current settings can be retrieved through the WaveformAnalyzer.GraphicItemVerticalLineParamsGet method and modified through the WaveformAnalyzer.GraphicItemVerticalLineParamsSet method.

 

For details about the use of the Waveform Analyzer refer to the How to use the Waveform Analyzer section.

For further details about methods of the Waveform Analyzer refer to the WaveformAnalyzer class section.
