Help me with the Interpretation of Waveform window in cadence.

Hi all ,

Here is the attached image ..


I want to know two things...

1)What i want to know is the interpretation in words of the Oval mark in the image.
Like this is the signal at the value of this...is there any variable..

2)On x-axis the signal which we sweeep in the dc analysis form appears and the output is on the Y axis.The signal which i am sweeping in the Parametric analysis is the signal whose waveform gets drawn...Is this always the case..Correct my above statement if its wrong...Or it all depends on the signals which i choose to be plotted in the output(ADE L)
