The standard way to typeset labels in metapost is using label(btex ... etex, pos), which uses TeX to typeset the label and then includes it in the metapost graphic. ConTeXt simplifies the user interface a little: instead of using btex ... etex, one can simply use label("...", pos), and the string argument is typeset using ConTeXt and included in the meapost graphic. However, both of these are cumbersome to use for dynamically generated labels (i.e., labels whose text depends on the value of some metapost variable). In this post, I show how to use fmtlabel, makes it simple to use dynamically generated labels.
