Well I tried the following
http://wikisophia.org/wiki/Wikisophia:Sandbox#Equations_with_numbers
<amsmath>
\end{displaymath}
\setcounter{equation}{1}
$$\label{eq:2} \int f dx = 0$$
\begin{displaymath}
\mbox{but now  and eq} (\ref{eq:2}).
</amsmath>

which as you can see does not work. As I said it is not very important
but I was just curious to see whether there is any sort of (quick and
dirty) hack to get reference to work, it seems not to be the case

You're  right,  Uwe;  on second thought: processing the
LaTeX twice from the backend would make references work, but
require twice as much processing time.

We should decide whether or not the trade-off is worth-
while.

Best, Peter

Well I sort of tried that too, editing the file for several times (but
may this is not what you are referring to.)

I think right now it would be best if the automatic numeration would
work (not the hack you described) and leave the label/reference for
later.

There is something I wanted to point out to you for a while although
it might sound off topic for the moment.

Do you know about preview-latex? This is mostly a brainchild of David
Kastrup. It is a lisp package for Emacs/Xemacs which inserts png
graphics for latex/tex files into the source buffer. It is now
integrated in auctex (http://www.gnu.org/software/auctex/), the
package which supports writing latex files in Emacs/XEmacs. The point
is some of the ideas/design of preview-latex went into LyX, the Latex
WYSISYW processor for Latex. May it would be worth to talk to David

### Plots / multiple functions in one plot

<!-- DIV {margin:0px;}-->
hi all

how can i use something like that

<plot>set samples 500
plot [-5:25][-0:455] -(1/3)*(x*x*x) + 8*(x*x) - 15*x
plot [-5:25][-0:455] -(2/3)*(x*x*x) + 7*(x*x) - 14*x
</plot>

this draw only ther first function

best regards gigo

### Re: Plots / multiple functions in one plot

     It  looks  like you already got it working, Enrico; but
just for future reference:

<plot>
plot [-5:25][-0:455] -(1/3)*(x*x*x) + 8*(x*x) - 15*x, -(2/3)*(x*x*x) + 7*(x*x) - 14*x
</plot>
