Name

gnuplot_open_pipeT_gnuplot_open_pipeGnuplotOpenPipeGnuplotOpenPipegnuplot_open_pipe — Open a pipe to a gnuplot process for visualization of images and control values.

Warning

gnuplot_open_pipegnuplot_open_pipeGnuplotOpenPipeGnuplotOpenPipegnuplot_open_pipe is obsolete and is only provided for reasons of backward compatibility.

Signature

Description

gnuplot_open_pipegnuplot_open_pipeGnuplotOpenPipeGnuplotOpenPipegnuplot_open_pipe opens a pipe to a gnuplot sub-process with which subsequently images can be visualized as 3D-plots (gnuplot_plot_imagegnuplot_plot_imageGnuplotPlotImageGnuplotPlotImagegnuplot_plot_image) or control values can be visualized as 2D-plots (gnuplot_plot_ctrlgnuplot_plot_ctrlGnuplotPlotCtrlGnuplotPlotCtrlgnuplot_plot_ctrl). The sub-process must be terminated after displaying the last plot by calling gnuplot_closegnuplot_closeGnuplotCloseGnuplotClosegnuplot_close. The corresponding identifier for the gnuplot output stream is returned in GnuplotFileIDGnuplotFileIDGnuplotFileIDgnuplotFileIDgnuplot_file_id.

Attention

gnuplot_open_pipegnuplot_open_pipeGnuplotOpenPipeGnuplotOpenPipegnuplot_open_pipe is only implemented for Unix-like systems because gnuplot for Windows (wgnuplot) cannot be controlled by an external process.

Execution Information

• Multithreading type: reentrant (runs in parallel with non-exclusive operators).
• Multithreading scope: global (may be called from any thread).
• Processed without parallelization.

This operator returns a handle. Note that the state of an instance of this handle type may be changed by specific operators even though the handle is used as an input parameter by those operators.

Parameters

Result

gnuplot_open_pipegnuplot_open_pipeGnuplotOpenPipeGnuplotOpenPipegnuplot_open_pipe returns the value 2 ( H_MSG_TRUE) if the sub-process could be created. Otherwise, an exception is raised.
