It's important to note that, after eventually removing graphic items through the WaveformAnalyzer.GraphicItemRemove method, you will have to perform a new call to the WaveformAnalyzer.GraphicItemsCountGet in order to have an update enumeration of graphic items and in order to avoid misalignments of the zero-based index when accessing the unique identification number of the graphic item through the WaveformAnalyzer.GraphicItemUniqueIdGet method.
