Dear List,
I am currently having problems drawing commutative
diagrams in algebra using the dcpic package in Lyx.
Everything works ok in LaTeX but if I use the same
codes on Lyx. I get errors. dcpic is a package that
allows drawing commutative diagrams, it needs pictex
.. so in the preamble I typed
\usepackage{dcpic,pictex}
then in the body of my document I wanted to draw a
diagram.. So I let LyX allow LaTeX code (ie. I
inserted an ERT).. and typed the following..
\begindc{\commdiag}
\obj(1,1){$A$}
\obj(3,1){$B$}
\obj(3,3){$C$}
\mor{$A$}{$B$}{$f$}
\mor{$B$}{$C$}{$g$}
\mor{$A$}{$C$}{$h$}
\enddc
Ok .. this worked.. but then when I type $\bar A$
instead of $A$ ... I get an hbox error, and the dvi
never shows the diagram ... I tried many things like
${\bar A}$ and some other tricks.. but all the time I
get an error.. However, when I tried my code with
$\bar A$ in LaTeX, I am able to make the diagram.
I am assuming that this is a LyX problem and not the
package, since this code works well on LaTeX. I would
appreciate any advise (especially on drawing diagrams
on LyX).
Sincerely,
Jose Capco
PS : Should one place tolerance values in the preamble
when working with LyX?
