XWaveName
XWaveName (graphNameStr, traceNameStr)
The XWaveName function returns a string containing the name of the wave supplying the X coordinates for the named trace in the named graph window or subwindow.
Parameters
graphNameStr can be "" to refer to the top graph window.
When identifying a subwindow with graphNameStr, see Subwindow Syntax for details on forming the window hierarchy.
traceNameStr is the name of the trace in question.
Details
XWaveName returns an empty string ("") if the trace is not plotted versus an X wave.
For most uses, we recommend that you use XWaveRefFromTrace instead of WaveName. XWaveName returns a string containing the wave name only, with no data folder path qualifying it. Thus, you may get erroneous results if the X wave referred to in the graph has the same name as a different wave in the current data folder. Likewise, if the named wave resides in a folder that is not the current data folder, you will not be able to refer to the named wave. Use XWaveRefFromTrace instead.
graphNameStr and traceNameStr are strings, not names.
Examples
Display ywave vs xwave // XY graph
Print XWaveName("","ywave") // prints xwave
