Graphics, Figures & Tables ⇒ xypic: rotate text and arrow thickness

[lauraf]

Hello all,

I have created the following diagram with xypic, which I would now like to tweak:

Specifically, I would like to:
1) rotate the text to be parallel to the arrows, and
2) change the arrow thickness.

I see from the xypic reference manual (attached) that this is done with the options "rotate" and "line", respectively, but I have not been able to figure out how to implement these changes. Any input would be much appreciated. I work with TeXShop on Mac OS X 10.5.

Many many thanks!
Laura

The scaling does work, but not with our example because you need to specify a back end. With dvips it does work, then too bad your using TeXShop, and thus presumably pdflatex, because they do not mix.

This works with latex + dvips

The recent update to xypic, with the addition of pdfxy (or whatever it was called) might help.

As for the rotation stuff, I've no idea how that show work. Actually I would not rotate the texts because it makes the text harder to read

Hi, many thanks for your reply.

Could you please tell me then how I can run this without using TeXShop? I have tried

latex filename.tex

from a terminal window, but this does not produce a pdf file.

Sorry if this is a basic question, but I don't really understand many of the technicalities --- like what a backend is

Thank you!
Laura

[daleif]

latex + dvips + ps2pdf, i.e.

latex file.tex (perhaps several times)
dvips file.dvi
ps2pdf file.ps

Backend usually refers to what ever is doing the real work. In this case we use the dvips backend which will do several things directly in PostScript that we cannot do in TeX alone

Great, thank you!
