Well, I thought that the variation won't be so big.

Thanks, it is really cleaner and shorter. The simple
things are so hard to see.

In general, I also prefer drawing after filling

I will surely check this. Thank you once again

Hi,

Is there a simple manner to include an image like pdf (created with a 
software) in a .mp code ? I've read things about image command but found 
nothing in Metapost manual

Thanks in advance

Hi. I've been looking for a long time for some clues on how to write block
matrices in LaTeX. I tried to use METAPOST, but the placement is non
trivial, and the result not allways satisfactory.

Do you have any experience on how to place efficiently lines in a (La)TeX
construction, like a matrix ?

Have you looked for a latex package on CTAN that would handle
this for you?  I know of one package (gauss.sty) that allows
one to typeset matrics with row/column operations denoted on
tehs ide of the matrix, much as one would do when doing an LU
or LDU decomposition of a matrix...

Hi, all.

I found out that when a figure has labels (with `btex' and `etex'),
then the whole figure does not appear in the .dvi file, but only in the .ps
file.
Is that normal, and how can I work it out?
On my PC I have Mandrake Linux 9.0.

Thanks,
Rodolfo

Hi Roberto,
Some months ago I had a similar issue with labels. I
posted a message with subject "MetaPost lables do not
appear" and I received several answers. They might
help you and you can read them here:

Subject: [MetaPost] Graph: Year/Month Units
To: metafont@ens.fr
MIME-Version: 1.0
Content-Type: text/plain; charset=us-ascii


I would like to produce a MetaPost graph (using the standard graph macroset)
with both the year (century plus year or bare year) and month along the x
axis.  Something more or less like the following:

     |
     |
     +--|----------|----------|----//----|-- ...
      99/11      99/12      00/01  //  00/12 ...

                Time (year/month)

(I'm using Red Hat 9, standard distribution.)

I wouldn't expect MetaPost to automatically know that values and separators
like the above are consecutive year/month units and treat them appropriately
(a na\"\i ve test predictably failed); I assume that some other format is
necessary.

Splicing the year/month into one full integer (for example, 199904) or a
decimal (1999.04) would distort the graph due to the large gap between the
twelfth month of one year and the first of the following.

The alternative is to simply use the number of months since the origin date.
While this is acceptable it does not---especially for several years' worth
of
data points---provide the clarity of a year/month combination.

Can MetaPost in fact accommodate such values?  Do I need to look into
gnuplot?

Thanks very much for any responses.

Hi, Ivan.

Yes, I remember very well that message from you,
that is still stored with its answers on my computer.
But your problem was different: the label (only the label, if I remember
well)
would not appear in the .ps file, whereas my problem is that the whole
figure
does not appear in the .dvi file, although it works fine in the .ps file.
That's why I posted a new message.
I'll have a look at the address you suggest, but I'm afraid I won't find an
answer to my own
question. I'll have a look anyhow.

Thanks indeed,
Rodolfo

Hi Roberto,
Some months ago I had a similar issue with labels. I
posted a message with subject "MetaPost lables do not
appear" and I received several answers. They might
help you and you can read them here:

Hi Rodolfo,
Unfortunately, I cannot help you very much. Although I
became quite skillfull in using MetaPost, I am not so
skillfull in understanding why and how it works
especially with labels. I hope that you or someone
else will find and post an answer.

However, my exact problem is that not only the labels
but whole parts of my figure did not appear in the
MetaPost ps output. I am attaching some files to
illustrate this (I am sorry they are long but I have
no time to shorten them):
images.mp is the metapost source
image2.tex is the latex file that includes the
metapost output.
 
So if you mpost images.mp and open the resulting
images.2 you will see that a great part of the figure
is missing.
But if you latex image2.tex and open image2.ps you
will see the whole figure.
This makes me think the explanation why your figure
does not appear in the dvi file, is close to the
explanations of my postings.

I would like also to ask you why do you want to work
with the dvi file. Up to now I pay little attention to
them.

Hope this helps

Regards Ivan Ivanov

The path doesn't have a counterclockwise orientation,

It is normal. The figures produced by metapost do not include the fonts
required to render them. You need to include the figure in a latex
document and process the result with dvips (or dvipdfm). This way, the
post-processor reuses the fonts used by the latex document if the figures
use the same fonts, or include the neccesary fonts if not. This reduces
the size of the final document file.

The dvi file do not include the images, actually. Instead, it only
includes to the file in which the image resides. The dvi viewer calls
ghostview passing it the name of that file, ghostview renders the image
and the dviviewer puts the resultant bitmap in the screen. The problem
with metapost graphics is that, as explained before, the file is
incomplete, because it lacks the fonts. So ghostview crashes and nothing
is visualized.

If you compile with pdflatex, you can obtain a PDF in a single pass, and
since the PDF actually includes the images, you can visualize it using
acrobat or xpdf without problems.
