Hi,
I don't know if I can explain the problem I'm having. I made a project with
14 chapters. In each of them, there are graphics embedding metapost code. I
proceed as follows : I compile each chapter alone with lmtx then I compile
the project containing the 14 chapters. I didn't encounter any problems
except with a graphic from the last chapter. It is indeed in chapter 14 but
not in the project ! I give the code for this graph.
Thanks.
Fabrice

H Fabrice,
You did not provide a good minimum test because the graph by itself renders fine:

Best wishes,

(if all else fails, you can replace \startMPcode with \startMPpage and generate a standalone graph that way)

Hi Taco,
I knew I wouldn't be able to explain what was happening.
The code works perfectly and the figure is clearly visible in the component
chapter-14 :
\startcomponent[chapter-14]
\startMPpage
...
\stopMPpage
\stopcomponent
But if I compile my project, it disappears !!
\startproduct[terminale-manual]
\startbodymatter
\component[chapter-1]
\component[chapter-2]
\component[chapter-3]
\component[chapter-4]
\component[chapter-5]
\component[chapter-6]
\component[chapter-7]
\component[chapter-8]
\component[chapter-9]
\component[chapter-10]
\component[chapter-11]
\component[chapter-12]
\component[chapter-13]
\component[chapter-14]
\stopbodymatter

it might be that you redefine something metapost

It is probably not related to the figure itself. Something may be different in this component compared to the other ones. I cannot really say, of course. Still, using external image instead of inline metapost may be fix it. Not elegant, but if it works it works!
Good luck,

Hi Hans and Taco,
@Hans, I compiled by commenting and uncommenting one component at a time;
it is component 5 which interferes with the metapost code of component 14
All I have to do now is find out what the cause is.

Hi,
Here is the code that interferes with the graph from the last chapter but
why ?
\startMPcode
pickup pencircle xscaled 1;
defaultfont := "texgyrepagella-regular*default" ;
defaultscale := 0.8 ;
path circle, p, q, b;
circle = fullcircle xscaled 5cm yscaled 3.5cm;
p = (point 2 of circle .. (-0.15cm,1.5cm)
..(0,0)..(0.15cm,-1.5cm).. point 6 of circle);
q = (subpath(0,2) of circle -- p -- subpath(6,8) of circle
--cycle);
b = (reverse p -- subpath(2,6) of circle -- cycle);
definecolor [ name = "mp:red", r = 1 ];
definecolor [ name = "mp:blue", r = 0.54, g = 0.17, b = 0.89 ];
fill q withcolor "mp:red" withtransparency(1,0.4) ;
fill b withcolor "mp:blue" withtransparency(1,0.4) ;
draw circle;
draw p;
label("$\overline{\text{A}}$",( 1.5cm,0));
label("$\text{A}$",(-1.5cm,0));
label.top("E",(0,1.85cm));

Because of this “path b”:

because there “b” is a now a path, not a numeric.
Adding
numeric a,b;
fixes the problem in chapter 14.
But why it does not affect chapters 6-13, that I do not understand.

Woundn't newnumeric be better?
There are very few instances where I want variables defined in one block to be reused in another block. So, I almost always use
\startMPcode
begingroup;
....
endgroup;
\stopMPcode
to avoid such issues.

Hi,
Thanks for your help. I did several tests playing only with the code of
component 5 which interferes with that of component 14.
@Aditya
begingroup;
.....
endgroup;
does not work.
@Hans
save defaultfont, defaultscale;
maybe also:
save circle, p, q, b ;
I get an empty rectangle in place of the graph in composant 5.
@Taco
The solution that works is to add component 14 to the code
numeric a, b;
