My Chop nodes are simple:
“Import”–>“Noise”–>“Export”

I want the parameter from Import node be the range (horizontal axis) of Motion View Pane instead of Frame,
because the parameter samples the x dimension of the Noise node's noise space,
if we plot the parameter into variable, we can see the relationship between the parameter and the noise , right now it appears as a horizontal line.

What I'm doing is procedural modeling not animation, though it works fine, I would still like to see the curve like relationship between channels.
