Calling gnuplot from ConTeXt

The easiest way to make plots in ConTeXt documents is

     \usemodule[gnuplot]
     \starttext
     \title{How to draw nice plots with {\sc gnuplot}?}
     \startGNUPLOTscript[sin]
     set format y "%.1f"
     plot sin(x) t '$\sin(x)$'
     \stopGNUPLOTscript
     \useGNUPLOTgraphic[sin]
     \stoptext

This will run gnuplot automatically and include the resulting figure in the document.
