LMTX and addplot table

LMTX and addplot table

[Jean-Philippe Rey]

[-- Attachment #1: Type: text/plain, Size: 965 bytes --]

Dear list,

I am unable to draw a plot using an external file with LMTX. Here is a minimal example

=====================
\usemodule[pgfplots]
\starttext
\starttikzpicture
\startaxis
\addplot table [x=t, y=E] {mfe-addplot.dat};
\stopaxis
\stoptikzpicture
\stoptext
=====================

The ConTeXt run fails with an "Undefined control sequence" error (see attached log file). I don't know if this is an LMTX or PGF issue. The example works fine with MkIV. I tried with the tikz version available on ConTeXt garden (pgf 3.0.1, pgfplots 1.16) and the last one from CTAN (pgf 3.1.7a, pgfplots 1.17) with the same result.

The same example works fine if I provide the data inline. This looks like a problem while reading the data file.

Thanks for your insight.

Best regards,

--

I am not really a tikz user but can run it here

wipe t-tikz.* on your machine in order to use m-tikz.mkiv in the 
distribution because it looks like it does a bad catcode table change 
... that went unnoticed because a chardef'd constant gets typeset (and 
when that happens before \starttext you won't see it but it actually 
does introduce some funny char); in lmtx we don't use chardef for that 
so that can give an error then when loading

anyway, you're not suffering from that i think but better use the right 
module loader anyway

then you can define the \PackageError macro (I did it with some trial 
and error but the next seems to work:

\let\PackageError\writestatus

so I'll add something like that to m-tikz.mkiv

after all that I get this:

PGFPlots: reading {mfe-addplot.dat}

! Package pgfplots Warning: the current plot has no coordinates (or all

  [warning /pgfplots/warning/plot without coordinates]

! Package pgfplots Warning: You have an axis with empty range (in 
direction y). Replacing it with a default range and clearing all plots.

  [warning /pgfplots/warning/empty range cleared axis]

which still looks bad but at least you don't crash .. i'll look into 
that later today (as i'm splitting mkiv/lmtx code i use a slightly 
different file reader so maybe that's it)

\PackageError is a LaTeX command which takes 3 argument: 
\PackageError{<package>}{<error>}{<help>}

I wiped t-tikz.  The only noticeable difference is that now I need to explicitly \usemodule[tikz] in order to use pgfplots. I checked and found the line

\usemodule[t][tikz]

in t-pgfplots.tex.  I guess that explains it.

As Wolfgang pointed out, \PackageError takes three parameters, the third is meant to be displayed when the user types H to an error prompt. I defined it as

\def/PackageError#1#2#3{\writestatus{#1}{#2 (#3)}}

that effectively displays the error message in the console and the log file.


> which still looks bad but at least you don't crash .. i'll look into that later today (as i'm splitting mkiv/lmtx code i use a slightly different file reader so maybe that's it)

I guess that you've pinpointed the problem.

By default, pgfplotstable breaks lines at white space (tab or space according to the pgfplotstable manual). I used tabs as column separators in my demo file. With MKiV, the columns are correctly split but with LMTX, pgfplotstable sees a single column.

I explicitly stated that the columns are separated with tabs:

\addplot table [x=t, y=E, col sep=tab] {mfe-addplot.dat};

and it works. I tried to change the columns separator to a space, instead of a tab and it also works.

I don't know what pgfplotstable uses to split columns, but the conclusion is that with MkIV 'col sep=space' means space or tab, whereas with LMTX it means strictly a space character.

Thank you very much for your help.

I think I have it running now but you have to wait for an update (one of 
those curious border cases where tex bends a rule by turning tabs into 
spaces (the alternative is to let the tab token flagged as spacer travel 
around which would permits round trip). Makes me wonder I should have 
that as option in luametatex (but as I'm now in metapost mode I delay 
that pondering.)

probably ... anyway, when we enable more strong protection of macros in 
context one needs the mentioned variant anyway (that way I can deal with 
it .. there a few tikz files in the test suite so they would bark when 
something fails)
