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.

gnuplot_plot_ctrl returns the value if there is an active gnuplot stream opened with gnuplot_open_pipe or gnuplot_open_file, if the data file for the current plot could be opened, and if only integer or floating point values were passed. Otherwise, an exception is raised.
