OK compiled and looking now. Would have been much faster with a complete MWE ;-)

I'm assuming IRL you have more than one class?

1010011010

No, just the one class. It's the only solution I found to colour those damn scatter points.

Workaround will do fine. Finishing the document by itself will be a challenge. heh

Paul Gessler

If it's only one class, there's no need for scatter

\documentclass[border=5mm]{standalone}
\usepackage{pgfplots}
\pgfplotsset{compat=1.10}

\begin{document}

\begin{tikzpicture}
\begin{axis}
\addplot[color=green,only marks]
      table[x=x,y=y] {
    x          		 y               class
    100			-160		1
    200			-35		1
    300   		-4.2       	1
    400 		9       		1
    500 		16.9       	1
    600  		21.3		1
};
\end{axis}
\end{tikzpicture}
\end{document}

should do you fine

(at least I think that's what you want)

1010011010

That's pretty much what I'm looking for, yup.

Thanks!

Paul Gessler

@1010011010 You're welcome; easy fix (this time :~) )!

@1010011010 pgfplots and TikZ are not the same thing, and if you look in pgfplots' manual, you'll find scatter.

Why even use unicode (not even real unicode) within mathematica?

egreg

@Johannes_B I can't understand what's the purpose in using such clearly buggy TeX code generators.

Johannes_B

@egreg Dito.

@egreg He spent more time investigating and changing and complaining than doing it properly by hand.

@egreg +1 from my side. And all this trouble for x and y? Insane.

Joseph Wright

@egreg To give us rep points :-)

egreg

@JosephWright :)

@Johannes_B Maybe the input is responsible for it.

Johannes_B

7:57 AM

@egreg Maybe.

egreg

@Johannes_B I don't know Mathematica, so I can't say more.

Nasser

What does this error please mean? I am trying egreg fix on my file but get this
Package hyperref Warning: Token not allowed in a PDF string (PDFDocEncoding):
(hyperref)                removing `math shift' on input line 44966.

! Unable to read an entire line---bufsize=200000.
Please increase buf_size in texmf.cnf.
>

do I need to find texmf.cnf file and edit bufsize in it as root?

may be this is what pdflatex.exe on windows was crashing.

Johannes_B

@Nasser Usually math chars and greek letters aren't allowed in pdf-bookmarks. Have a look at \texorpdfstring{$a+b=c$}{a+b=c}

Nasser

@Johannes_B thanks will do that. I got those error about the PDFDocEncoding before many times and was meaning to look at them, but the pdf file was being generated ok. I am asking about the texmf.cnf issue now. THis is the first time I saw this. Ok, Will search for this file in my linux system and see if I can edit it for some larger value for now, I just need to verify the fix by egreg now.

egreg

@Nasser If an input line is longer than 200000 characters, TeX can't read it into memory; you might enlarge the buffer size, but such long input lines are not really useful.

@Nasser And a warning is not an error; don't mix them. The “token not allowed” warning just tells you that you have $ in a section title.

Nasser

8:12 AM

@egreg I am searching now to change the size. I know, but these are auto-generated latex from running large test cases, and everything runs as script and I do not have a check setup in the process for what size solutions are generated by Maple and Mathematica.

@egreg I make the section title as the equation itself, so that is why I need math in there. I make the equation itself as the section title, so that one can click on it in HTML and go to the equation. it does work actually pretty well, even with those warnings, so that is why I ignored them :)

egreg

@Nasser I guess that a Mathematica worksheet is better.

@Nasser No, thanks. ;-)

@Nasser I decided long ago that differential equations were not my cup of tea. ;-)

Nasser

9:21 AM

I changed texmf.cnf to
buf_size = 10000000
main_memory = 50000000
and run fmtutil-sys --all
as root. but all constants are globbered now.
>pdflatex KERNEL.tex
Ouch---my internal constants have been clobbered!---case 14
I guess I used too large values?

This is a summary of all `failed' messages:
`pdftex -ini  -jobname=amstex -progname=amstex -translate-file=cp227.tcx *amstex.ini' failed
`pdftex -ini  -jobname=cont-en -progname=context -8bit *cont-en.mkii' failed
`pdftex -ini  -jobname=cslatex -progname=cslatex -etex cslatex.ini' failed
`pdftex -ini  -jobname=pdfcslatex -progname=pdfcslatex -etex cslatex.ini' failed

I'll reset the numbers to something smallers and try again

@PauloCereda Good morning!

Paulo Cereda

@egreg Good morning! :) How are you? :)

egreg

@PauloCereda Fine, thanks. The train has air conditioning and it's even working! You arrived late, I was already almost rep capped. ;-)

Paulo Cereda

@egreg Oh my! :) Out of curiosity, how many rep cap days in total? :)

David Carlisle

@PauloCereda up to his usual tricks, trying to steal my tick

Paulo Cereda

@DavidCarlisle Oh no! :)

What about the cricket match?

David Carlisle

10:38 AM

@PauloCereda he was trying to use Joseph's package to replace one of mine, but failed of course

@PauloCereda was there a cricket match?

Paulo Cereda

@DavidCarlisle How rude. :)

egreg

@PauloCereda That's something to be computed on the database, you're the expert.

@DavidCarlisle Yes, like there was a semifinal Brazil-Germany.

Paulo Cereda

@egreg I'll take a look later on then. :)

@egreg Nightmare fuel.

@DavidCarlisle England lost then. :)

David Carlisle

@PauloCereda It's not clear they even turned up to play the game:-)

Paulo Cereda

@DavidCarlisle Uh-oh. :)

David Carlisle

10:43 AM

@PauloCereda typical review of the match (by a former England captain) "It's been absolutely pathetic from England. What was said in the dressing room at lunch? To come out and play all those shots, it's ridiculous. We've seen some collapses in the last year - against Australia, Sri Lanka and now India - but this is the worst of the lot. Something has got to change."

Paulo Cereda

@DavidCarlisle Ouch. I probably need to summon my cricketeer duck again. :)

egreg

@DavidCarlisle With a much better answer, of course.

Hiya, can't seem to find an answer to this. I wish to redefine a color (some package uses a colour I find obtrusive and I wish to redefine it). But \redefinecolor doesn't do anything. :-(

hi there

am trying to include a png with transparency

(has chessboard background when opened with standard image viewer)

in the compiled pdf, the original background is showed (rather than the desired white)

what to do? first-aid?

1010011010

@nuttyaboutnatty Textbook example of a case where you'd show the code, don't you think ? :-)

nutty about natty

don't want anything fancy like gradients etc

@1010011010 you mean, MWE ?

David Carlisle

@1010011010 definecolor allows redefinition

nutty about natty

hear mention about png > eps

could do so via "convert" cmd or directly via gimp (from the original image) - iff necessary / recommended...

Paulo Cereda

11:19 AM

@nuttyaboutnatty MWE + image is needed. :(

At least, the image.

@PauloCereda I commented

Paulo Cereda

@egreg Grazie. :)

@PauloCereda the image itself must be the problem, I'll try and tweak the export options

1:08 PM

@DavidCarlisle (!!!) I thank you

Joseph Wright

@egreg About 10 times my rate :-)

egreg

@JosephWright You're too much into cricket. When is the next test?

Joseph Wright

@egreg July 27th, Rose Bowl, Southampton (Hampshire)

David Carlisle

@JosephWright pray for rain?

@1010011010 I wondered about doing \newcolor \renewcolor but it was extra code and extra documentation and I couldn't see the point so we just did \definecolor :-) the lack of "new" in the name is supposed to be a clue.

1010011010

@DavidCarlisle Inconsistency stems from those assumptions, though, don't you think? ;-)

Joseph Wright

1:20 PM

@DavidCarlisle Yup

David Carlisle

@1010011010 remember that we only had a few bytes and command names to spare (less than 50 command names spare in emtex after you loaded amsmath) and unlike redefining a command redefining a colour is unlikely to make things really break so having separate renew... didn't seem that useful.

1010011010

Yeah, from a developer's perspective, I get where you're coming from.

Johannes_B

@Stefankottwitz @cgnieder Why did i miss tikz.de? I noticed it last week. How was it introduced?

cgnieder

1:54 PM

@Johannes_B Another of @StefanKottwitz' ideas. I only know of it because Stefan asked me if I could post something there. I'm sure you can post there, too, if you want

:)

Johannes_B

@cgnieder I would, but i don't know much about Tikz. :-(

cgnieder

@Johannes_B Me neither... but don't tell anyone

Johannes_B

@cgnieder :-D

nutty about natty

2:44 PM

@PauloCereda weird, whereas upload.wikimedia.org/wikipedia/commons/4/47/… works both in html and in the compiled TeX, my *.png works only in html (and in the default image viewer) - but not in the compiled TeX

hence I figure that the "type" of transparency might differ between the two png's

so maybe there is a tweak to the code which will "show" transparency

(used exact same code for upload.wikimedia.org/wikipedia/commons/4/47/… though...)

"First tests show that this works for some images only. "My" image of course does not work ... " - tex.stackexchange.com/questions/86500/…

David Carlisle

@Johannes_B make a post saying how good \begin{picture} is.

1010011010

Could anyone clarify this step from this question: http://tex.stackexchange.com/questions/119714/create-oml-font-encoding-from-a-commercial-font

I created a file ptmm.map with the single line: `ptmmi8r NimbusRomNo9L-ReguItal "TeXBase1Encoding ReEncodeFont" <8r.enc <utmri8a.pfb` This required a bit of research as I had to dig out the pdftex.map file from my installation to just copy the line with `ptmri8r` to the one above.

Where does ptmmi8r come from? I use font maps for my own fonts and they don't show up in in pdftex map file

egreg

@1010011010 ptmmi8r is the TFM file just created.

1010011010

@egreg My pdftex.map file does contain that entry, but does not contain any fonts I installed through otftotfm. How does that work?

egreg

3:01 PM

@1010011010 pdftex.map is written when you run updmap-sys. Unless you add new material with -enable-map or in a updmap.cfg file and run updmap-sys, the file doesn't change. However, you can load a map file or even a single map line with \pdfmapfile or \pdfmapline.

1010011010

@egreg I regularly use \pdfmapfile. How do I include an arbitrary tfm file? I have two tfm files here that I wish to add as math font.

I'm aware of e.g. the declaration \DeclareSymbolFont{letters}{OML}{cmm}{m}{it}.

I also looked here: tug.org/fonts/fontinstall.html

kpsewhich --var-value TEXMFLOCAL doesn't return a directory. It just returns .texlive/2013/.../texmf-local or something. So I did a full system search and none of the paths make any sense.

I'll stick it in a question. This is getting too complicated for chat. :-)

egreg

@1010011010 ?

David Carlisle

@egreg I couldn't have said it better myself:-)

egreg

@DavidCarlisle Short and to the point. ;-)

1010011010

Regardless of any complications; I think the public may also benefit from some clarification here and there (surely I'm not the only one with this problem).

David Carlisle

@egreg most unlike you!

Software bloat

Software bloat is a process whereby successive versions of a computer program become perceptibly slower, use more memory/diskspace or processing power, or have higher hardware requirements than the previous version whilst making only dubious user-perceptible improvements. The term is not applied consistently; it is often used as a pejorative by end users to describe undesired user interface changes even if those changes had little or no effect on the hardware requirements. In long-lived software, perceived bloat can occur from the software servicing a large, diverse marketplace with many differing...

egreg

@1010011010 A TFM file should live in a directory <root>/fonts/tfm/<family>, where <root> is TEXMFMAIN, TEXMFLOCAL or TEXMFHOME; <family> is any name you like.

tohecz

@DavidCarlisle you sure know to be cruel :D

egreg

@tohecz He's thinking to MathML

David Carlisle

3:18 PM

@tohecz I wasn't replying to any comment in particular

tohecz

@DavidCarlisle no, of course not.

David Carlisle

@egreg can't be that: MathML is a language not any software

egreg

@tohecz Correction: he's thinking to software implementing MathML (after any new specification release).

tohecz

@egreg we all love MathML :P

Paulo Cereda

@DavidCarlisle Bah you need to learn a new lingo:

Feature creep

Feature creep, creeping featurism or featuritis is the ongoing expansion or addition of new features in a product, such as in computer software. Extra features go beyond the basic function of the product and so can result in over-complication rather than simple design. == Causes == The most common cause of feature creep is the desire to provide the consumer with a more useful or desirable product, in order to increase sales or distribution. However, once the product reaches the point at which it does everything that it is designed to do, the manufacturer is left with the choice of adding unneeded...
