<div dir="ltr">Dear Christoph,<div>I tried to change second and third coordinates but the result remains the same. Also, coordinates aren't that of the lower left corner, and they are different for different labels, so I don't think this is the problem.</div>
<div>In fact, this .tex file is automatically generated by a script, and I'm almost sure that someone can compile this .tex file without any problems. I think the problem is in my MiKTeX dvips program converting dvi file to ps, but I don't know how to fix that.</div>
<div>Best regards,</div><div>Andrei Petrov</div></div>
