Plot control values using gnuplot.
::gnuplot_plot_ctrl displays a tuple of control values using gnuplot. If there is an active gnuplot sub-process (started with ::gnuplot_open_pipe), the image is displayed in a gnuplot window. Otherwise, the image is output to a file, which can be later read by gnuplot. In both cases the gnuplot output stream is identified by GnuplotFileID.

GnuplotFileID (input_control) |
gnuplot_id -> HTuple.long |
| Identifier for the gnuplot output stream. | |
|
Values (input_control) |
number-array -> HTuple.double / long |
| Control values to be plotted (y-values). | |
::gnuplot_plot_ctrl returns the value if GnuplotFileID is a valid gnuplot output stream, if the data file for the current plot could be opened, and if only integer or floating point values were passed. Otherwise, an exception handling is raised.
