This Nuke plugin mimics good old Shake's plotScanline.
It basically scans one line and creates a graph representing the RGB values.
The values are mapped to fit within the height of the image.

Knobs description:
Slice: decides which image row to scan
Gain: allows you to change the height of the graph curves
Mix: lowering this value will reveal the processed image

The plugin also displays the slice it's graphing by two openGl arrows that sit on the left and
the right image edge at the height of the slice.

Source code included.
Compiled for Nuke6.1->linux64 and Nuke6.2->win32, win64

Enjoy and drop me a line if you have any questions.
