The waveform display conditions are given a name and are saved. The saved display
conditions can be used again to display a waveform again. In this manual, saved
waveform display conditions are listed as a graph. The same applies for [Graph] on the
DAQManager software display screen.
Graphs can be searched by save time or graph name text string.
