[NTG-context] About Pgfplot.-

2023-07-22 Thread Freddy Omar López Quintero
Hello!

I’m trying to reproduce the example in https://wiki.contextgarden.net/Pgfplot 
and I’m getting this error:


tex error   > tex error on line 926 in file pgfcorepoints.code.tex: Missing

Please don't say '\def cs{...}', say '\def\cs{...}'. I've inserted an
inaccessible control sequence so that your definition will be completed without
mixing me up too badly.

[NTG-context] Fonts in same directory.-

2016-08-16 Thread Freddy Omar López Quintero
Hello!

Today I was working perfectly but after an OS update, I started to have
some problems with fonts.

In particular, I use to put the font files (.ttf) in the same directory
where .tex are placed, but now I'm getting this message:

simplefonts > font ''avenirnext'' not found


but I have not moved the font files.

Could you please give some advices to solve this issue?

In this link you guys can check a simple example of my compiling:

[NTG-context] Math using sans serif font and problems with the alignment

2016-06-10 Thread Freddy Omar López Quintero
Hello!

Some days ago, I asked about how to use sans serifed font in all math
document. My approach, given those answers, was create a little function to
use the serif fonts in math (using \definestartstop) but, when there is
some align involved, it produces an error :-\ .

An example is the following:


%
\definefontfamily [mainface] [ss] [Latin Modern Sans]

\definefallbackfamily [mainface] [mm] [Latin Modern Sans]
[preset=math:digitsnormal]
\definefallbackfamily [mainface] [mm] [Latin Modern Sans]
[preset=math:digitsbold]

\definefallbackfamily [mainface] [mm] [Latin Modern Sans]
[preset=math:uppercasenormal]
\definefallbackfamily [mainface] [mm] [Latin Modern Sans]
[preset=math:uppercaseitalic]
\definefallbackfamily [mainface] [mm] [Latin Modern Sans]
[preset=math:uppercasebold]
\definefallbackfamily [mainface] [mm] [Latin Modern Sans]
[preset=math:uppercasebolditalic]

\definefallbackfamily [mainface] [mm] [Latin Modern Sans]
[preset=math:lowercasenormal]
\definefallbackfamily [mainface] [mm] [Latin Modern Sans]
[preset=math:lowercaseitalic]
\definefallbackfamily [mainface] [mm] [Latin Modern Sans]
[preset=math:lowercasebold]
\definefallbackfamily [mainface] [mm] [Latin Modern Sans]
[preset=math:lowercasebolditalic]

\definefontfamily [mainface] [mm] [Latin Modern Math]


\definestartstop
[formulass]
[
before={\startformula
\setupbodyfont[mainface]},
after=\stopformula
]


\starttext

abcdefg ABCDEFG 123456 i

\startformula
{\tf abcdefg\,ABCDEFG} \quad abcdefg\,ABCDEFG \quad 123456 \quad
{\bf 123456}
\stopformula

% it works:
\startformula
Y=X\beta+\varepsilon
\stopformula

% it works:
\startformulass
Y=X\beta+\varepsilon
\stopformulass

% it doesn't work:
\startformulass
\startalign[n=4]
\NC  Y_t \NC = \beta_0 \NC + \beta_1  x_t \NC + \varepsilon_t \NR
\NC  Y_t \NC = \beta_0 \NC + \beta_1  x_t \NC + \varepsilon_t \NR
\stopalign
\stopformulass


\stoptext
%


Could you please give me some advices?

Thanks in advance!

[NTG-context] Fonts distributed with a ConTeXt document

2016-05-30 Thread Freddy Omar López Quintero
Hello!

Sorry if the answer is obvious but I have no found how solve this problem.

I would like share a document written using ConTeXt that employes different
fonts, but the recipients have no possibilities to install those fonts in
their computers.

​It is possible use fonts that are in the same directory that the .tex
document?​

​My folder is something like:

./context.tex
./font1.ttf
./font2.ttf
...
./fontn.ttf


Thanks in advance!​

[NTG-context] Fonts inside eqno{}

2016-04-29 Thread Freddy Omar López Quintero
Hello all!

I'm interested in change the natural numbering of one equation with \eqno{}
but it does not follow the main font selected.

A minimal example:

%%
\usemodule[simplefonts]
\setmainfont[Linux Biolinum O]
\setmathfont[Linux Biolinum O]

\starttext

I have the following expression

\placeformula
\startformula
y = Z \beta_1 + Y \beta_2 + u
\stopformula

that changes to

% \placeformula
\startformula
y = Z \beta_1 + Y \beta_2 + W_1\tau + u \eqno{ (1')}
\stopformula

\stoptext
​%%​

​I would like the (1') ​keep the same kind of font than (1).

Any hint will be appreciated.

Thanks!
