Displays a dynamic 1-d plot of a line in the image while the image

may have to resize the Camera window. Hold down the mouse button

These two macros continuously integrate and display frames either off-chip, using the Scion AG-5, or on-clip, using the Scion LG-3 and a Coho 4910 series camera. Press and hold the mouse button near the top of the Camera window to decrease the number of frames integrated. Press near the bottom to increase the number of frames integrated. Press above or to the left of the Camera window to stop integrating.
