This file should be imported through gp.py, which in turn should be imported via 'import Gnuplot' rather than these low-level interfaces. c:eZdZdZdZdZdZdZdZdZ dZ dZ dZ dZ dS) GnuplotOptsaoThe configuration options for gnuplot on generic platforms. Store the options in a class to make them easy to import and modify en masse. If you want to modify the options from the command line or within a running program, do something like the following:: import Gnuplot Gnuplot.GnuplotOpts.gnuplot_command = '/bin/mygnuplot' gnuplotx11z| lprN)__name__ __module__ __qualname____doc__gnuplot_commandrecognizes_persistprefer_persistrecognizes_binary_splotprefer_inline_data support_fifoprefer_fifo_data default_term default_lprprefer_enhanced_postscript1/usr/lib/python3/dist-packages/Gnuplot/gp_java.pyrrsS   ONLLK!"rrrN)Thread)RuntimectjS)zADetermine whether gnuplot recognizes the option '-persist'. )rr rrr test_persistr3s  ))rceZdZdZdZdZdS)OutputProcessorzKIn a separate thread, read from one InputStream and output to a file. cv||_||_tj|||ddS)Nr)inputoutputr__init__ setDaemon)selfnamer r!s rr"zOutputProcessor.__init__@s:  d### qrc |jt|j?N)r!writechrr readr$s rrunzOutputProcessor.runGs6 6 K  c$*//"3"344 5 5 5 6rN)rr r r r"r,rrrrr;s<66666rrc8eZdZdZd dZdZdZdZdZdZ dS) GnuplotProcessaUnsophisticated interface to a running gnuplot program. This represents a running gnuplot program and the means to communicate with it at a primitive level (i.e., pass it commands or data). When the object is destroyed, the gnuplot program exits (unless the 'persist' option was set). The communication is one-way; gnuplot's text output just goes to stdout with no attempt to check it for error messages. Members: Methods: '__init__' -- start up the program. '__call__' -- pass an arbitrary string to the gnuplot program, followed by a newline. 'write' -- pass an arbitrary string to the gnuplot program. 'flush' -- cause pending output to be written immediately. Nc| tj}tjg}|r2tst d|dt tjd}|||_ td|j tj |_|jtd|j tj|_|j|j |_dS)a Start a gnuplot process. Create a 'GnuplotProcess' object. This starts a gnuplot program and prepares to write commands to it. Keyword arguments: 'persist=1' -- start gnuplot with the '-persist' option, (which leaves the plot window on the screen even after the gnuplot program ends, and creates a new plot window each time the terminal type is set to 'x11'). This option is not available on older versions of gnuplot.
