4.4 Create a Profile view
A profile graph shows the voxel value along a 3D trace (profile). This allows you to analyze the
voxel value distribution of a 3D object in various ways, as an aid in setting up 3D processing
(e.g., thresholding).

On the profile view:
○
The horizontal axis is the position in millimeters along the trace and the vertical axis is
the pixel intensity values as a function of that position.
○
Press <Shift> to display the pixel intensity from the location of the 3D cursor. Click and
drag the white line to move it, which in turn, moves the cursor on the image.
