Hi Oliver,

using the newest version of ImageJ (1.40c), I have no problem
with x_min & x_max for 32-bit images.

For 16-bit images, the histogram includes all values (0-65535),
so it has all the information that you can have.
Unfortunately, the screen resolution does not show it, and
currently I see no easy way to show it from a macro (except
converting the image to 32 bit).

For the "Log" (logarithmic y axis) feature, use
   setKeyDown("shift");
before issuing the run("Histogram"...) command.
