org-babel-gnuplot: variable expansion in gnuplot source-code with '$' character 

Variable names in gnuplot source code preceded by the '$' character
  will be expanded to their value before the code is executed.  For
  example the following will results in the evaluation of 'plot
  sin(x)' by gnuplot.

  "sin(x)"

  plot $fun
