Dear Otfried, In the preamble I have added: \usepackage[miktex,siunitx]{gnuplottex} \usepackage{siunitx} and in the paragraph mode: \begin{gnuplot}[terminal=cairolatex] plot sin(x)/x \end{gnuplot} but it does not work, probably because pdflatex needs -shell-escape option in the command line. How to do it in IPE? Thanks in advance Jerzy
