Thanks Wolfgang, your solution does perfectly what I do need.
I guess the \offset trickery can be used for other floats as well, when fine tuning is necessary.

Many thanks again: OK

Hi all,

How is it possible to have a STEPchart be midaligned, or right-aligned, as one may do this with figures, tables, and FLOWcharts?
An example is here:

%%%%%%%%%%%%
\usemodule[steps,mathml]
\starttext
\startbuffer[test-chart]
\startSTEPtable
\cell {$c=2a+3b$} \text {with $a=5$}
\cell {$c=10+3b$} \text {and $b=6$}
\cell {$c=10+18$} \text {we get}
\cell {$c=28$}
\stopSTEPtable
\stopbuffer
How can one center the following \type{\STEPchart}?
\getbuffer[test-chart]
\stoptext
%%%%%%%%%%%%

I should add that \startalignment[middle], or \placefigure do not have any influence on the alignment of the above example.
  
You have to adjust it by hand, stepchart use the complete textwidth and alignments
is useless in this case, use \offset to shift the chart to the right side.

\offset[x=.3\textwidth]{\getbuffer[test-chart]}

Wolfgang
