I cannot reproduce this problem.
Note that a linewidth=4 will draw a tick line on the screen and you may not notice
the difference with PostScript if you print on a high resolution printer.
Just to check, try to set teh linewidth=20 and let me know.

A problem in computing the right scale has been fixed in version 1.01.
You can set the plot scale by creating an empty 2-d histogram :
