setting 0,0 in image

[Roger Phillips]

I am displaying (plotting) 3D data (X,Y,time) in a stack, drawing lines and
measuring intersections.  I would like to set the 0,0 point at the middle of
the image/plot to accommodate negative values; is this possible?
Alternatively, I could use plot.create but is there any way to make multiple
slice plots?
Thanks for any help,
Roger
