Macro

(with-gnuplot-instance (stream &rest args) &body body)

start an external gnuplot process with a data input stream open for the extent of body.

stream is bound to gnuplot's input stream. Printing to it is equivalent to printing into a file read by gnuplot as a dataset with its plot command.

args are arguments sent to #'launch-gnuplot.

Leaving the macro is equivalent to gnuplot reaching EOF when reading an external dataset.
