MetaPost, in fact Metafun, has extensions to include external figures

If I understand, but I'm not sure at all, calculating (xmax-xmin) / 10

It works. But how to choose not to avoid this problem (/10 or /20 or ) ?

the images are not adjusted to the BoundingBox.

This code runs fine:
\startMPcode
label.bot(btex Metapost and Statistics etex,(5mm,0)) ;
\stopMPcode
Also, this code run fine:
\startMPcode
input mps-core.mp;
draw fullcircle scaled

Hello all,
Is it possible to define a path in metapost-metafun using function? In
the metafun manual (chapter on Functions) the examples shown are all of
the type draw function I wonder if it is possible to define a path
with a function (picture after draw doesn't allow that afaik)?

Thanks for the code, the stretching is ok (can be hand-tuned) but I find
the positioning a bit odd. Look at the additions to your example:
--
\starttext
\useMPlibrary[txt]
\startsetups text-a
\startuseMPgraphic{followtokens}
path RotPath ; RotPath := reverse

Hello list,
How can I call the \followtokens macro (or a similar solution) from within
metapost? Specifically, I want to integrate text between the semi-circle
arcs in a rainbow-like structure (with the text placed inbetween the arcs,
that should alsó be drawn). The text should not be stretched

The minimal example works with your version, but the old MetaPost
code does not. The def variant works fine with both.
ok
2) Replace
startplaincompatibity → startplaincompatibility
stopplaincompatibity → stopplaincompatibility

3) This one is truly optional and just a suggestion for a better
interface. Although it's nice to have the grouping
on traditional MetaPost.
Is this prefix required? It breaks old code and required a branch in
every new project. And I don't really see a reason for this
incompatibility. Here is an example defining a new direction “foo”:
\starttext
\startMPcode
label(first, origin);
%% MkIV
%% pair
. And likewise, code using the
mpfun_ prefix fails on traditional MetaPost.
So is anyone using mkiv still using MkII?

I wasn't aware of users defining extra ones. I'll add this:
Probably not many users will tinker with custom label directions,
but MetaPost package authors do. Some packages like piechartmp¹
internally use laboff.foo and the mpfun_ prefix

labxf.foo := labyf.foo := 1 ;
