The \Chromato macro is an example application for the positioning environment. I've written it for my brother, who is writing a thesis in chemistry[[Chemistry]].

A downloadable version of the macro is available <texcode>\newdimen\Width \newdimen\Height\define[3]\Chromato{% \setbox\scratchbox\hbox{\externalfigure[#1][width=0.6\makeupwidth]}% \setuppositioning[unit=pt] \Width=\wd\scratchbox \Height=\ht\scratchbox \placefigure[][mediafig:chromatograms#1]{#2}{\startpositioning \position(0,0){\externalfigure[#1][width=0.6\makeupwidth]}#3% \stoppositioning}}\define[3]\LRposition{\edef\YPos{\withoutpt{\the\dimexpr(\withoutpt{% \the\dimexpr(#1pt/100)}\Height - 0.tex|here1\baselineskip)}}% \position(#2,\YPos){\vbox to 2pt{\vss{\hbox to 0pt{#3}\vss}}}}\define[4]\Lbrace{\LRposition{#1}0{\hss\rotate[rotation=90]{% $\overbrace{\hskip#2\Height}^{\rotate[rotation=270]{#4}}$}\hskip#3em}}\define[4]\Rbrace{\LRposition{#1}{\withoutpt{\the\Width}}{\hskip#3em \rotate[rotation=270]{$\overbrace{\hskip#2\Height}^{% \rotate[rotation=90]{#4}}$}\hss}}\define[2]\Lpfeil{\LRposition{#1}0{\hss{\tx#2} $\rightarrow$}}\define[2]\Rpfeil{\LRposition{#1}{\withoutpt{\the\Width}}{$\leftarrow$ \tx#2}}\define[3]\Oposition{\edef\XPos{\withoutpt{\the\dimexpr(\withoutpt{% \the\dimexpr(#1pt/100)}\Width)}}% \position(\XPos, and a PDF example of -\withoutpt{\the output \dimexpr(#2\baselineskip)}){% \hbox to 0pt{\hss#3\hss}}}\define[2]\Oben{\Oposition{#1}{0.8}{\tx#2}}\define[media:3]\Obrace{\Oposition{#1}{2.5}{$\overbrace{\hskip#2\Width}^{\hbox{#3}}$}} \starttext\Chromato{ecolizeit}{Expression der rekombinanten Fucosyltransferase~V in {\it E.~coli}.}{%\Oben5{BRS} \Oben{15}1 \Oben{26}2 \Oben{38}3 \Oben{50}4\Oben{61}5 \Oben{72}6 \Oben{83}7 \Oben{94}8\Obrace{49}{0.pdf|here]]68}{\tx1--7}\Lpfeil{12}{97\,kDa} \Lpfeil{20}{66\,kDA}\Lpfeil{32}{45\,kDa} \Lpfeil{52}{31\,kDa}\Lbrace{40}{0.8}{4}A \Lbrace{90}{0.2}{0.1}B\Rpfeil{29}{FucT~V} \Rpfeil{87}{FucT~V}\Rpfeil{40}1 \Rpfeil{80}2 \Rbrace{60}{0.4}3{\txx1--2}}\stoptext</texcode>

(A [[media:chromatograms.tex|downloadable version]] of the macro is also available.) The resulting figure looks like this, though you'll have to imagine the graphic. The output with the graphic included can be downloaded [[media:Chromato.pdf|here, in pdf form]]. <small><precontext>
