Inconsistent results with the examples in Data Analysis Tutorial

(Sorry for the re-post, but the attached files seemed not to show correctly.)

Dear all,

Upon following the example given in the MPB Data Analysis Tutorial, I
got an inconsistent result.

According to the tutorial,
http://ab-initio.mit.edu/wiki/index.php/MPB_Data_Analysis_Tutorial#The_tri-rods_dielectric_function
my dielectric function should look like the attached file, Tri-rods-eps-2.gif.
However, what I got looks like the other attached file,
ubuntu_result.png, which is a 90-degree-rotated version of the example
in the tutorial, the original distorted image is the same with that of
the example, though.
To rule out any typo, I directly ran the example provided with the MPB
package of my linux distro, but the dielectric function was still the
rotated version of the tutorial example.
And I think these two dielectric functions are not the same.
I did some search on this mailing list without any finding of posts
related to the same problem.  So, I wonder it's just me.

FYI, my simulation was performed under Ubuntu linux desktop i386 7.04 and 6.10.

Any comment would be very appreciated. Thanks very much.
