## Description

Shows or hides the Eye Contours identification legend on the Waveform window. If multiple channels waveforms are shown with legends all of the displayed legends are controlled by this setting. The legend identifies the individual eye contour lines on a waveform. To expand or contract all displayed eye contour legends, use the `:DISPlay:WINDow:TIME{N}:LEGend:ECEXpand` command. Use the `Eye Contour Configuration Commands` to create and display contour lines. If Option 200, Enhanced Jitter Analysis, is also installed, the application leverages the oscilloscope's ability to measure ultra-low levels of Random Jitter (RJ). This can be used to obtain fixed RJ values.
