Change of cvs at 2007-08-31 Ethan Merritt only for x11 but not for win

[Tatsuro M. <tma...@ya...>]

Dear Ethan Merritt

I have tested gragh plotting by a cvs(08-02-02) version (4.3) of pgnuplot+wgnuplot using a little bit
old octave (2.9.17, which does not send binary data from pipe).

(CVS wgnuplot was downloades from the following
http://www.ring.gr.jp/pub/text/TeX/ptex-win32/utils/ )

The mouse zooming was not possible.

I would like to confirm whether the change at 2007-08-31 after '***************'for only for x11
terminal but not for win terminal or not.

It can be readable the change is not x11 specific.
Are there other possibilities?

Regards

Tatsuro

	Version 2.9.? of Octave switched to piping all data to gnuplot in-line
	rather than via a temporary file.  This broke mouse zooming and replot.

	This patchset is an imperfect fix with several known problems:
	- Clipping of zoomed 3D contour plots is not correct.
	- splot volatile with image + zoom + unzoom is flaky
	- plot -> zoom -> set grid -> unzoom   loses the grid setting.
	- you cannot toggle log scaling on/off while using refresh.

	Introduce a new command "refresh" that acts like replot except that it
	does not re-read the input data.  Refresh is always needed in order to
	zoom or replot in-line data (input file '-'), but may optionally applied
	to normal data files also by appending the attribute 'volatile'.

	* src/plot2d.c (eval_plots): This is the core change. Instead of 
	freeing stored data after each plot, keep it around in case of a
	refresh command. The old data storage is freed at the start of the next
	"plot" or "replot" command.  This is parallel to what the 3D code was
	already doing. Set refresh_ok = 2  at the end of a successful plot.

	* src/plot3d.c (eval_3dplots): Update comments and remove dead code.
	Set refresh_ok = 3  at the end of a successful plot.

	* src/plot2d.c (refresh_bounds) src/plot2d.h
	* src/plot3d.c (refresh_3dbounds) src/plot3d.h:
	Provide a mechanism to recheck the INBOUNDS/OUTBOUNDS status of 
	existing data points after changing the current axis limits.

	* src/command.c (refresh_command refresh_request) src/command.h
	src/gadgets.c src/gadgets.h src/tables.c:  New command "refresh" that
	acts similarly to "replot" except that it does not re-read input data.

	* src/axis.h (AXIS_UPDATE2D): Save/restore axis limits for zooming.

	* src/mouse.c (apply_zoom): Choose between refresh or replot depending
	on whether the current plot contain volatile data.

	* src/mouse.c (builtin_toggle_log): Ignore 'l' and 'L' for volatile data

	* src/set.c (set_logscale) src/unset.c (unset_logscale):
	Because setting or unsetting log scale changes the way input data is
	stored, "refresh" cannot work if the log setting has changed.
	Set a flag indicating that a full replot is necessary.

	* src/datafile.c (df_open): Accept a "volatile" keyword to indicate
	that data in the input file may change. If data is input from pseudo-
	device '-' or from a file marked "volatile", set a global flag so
	that mousing/zooming/etc can choose to refresh rather than replot.

	* docs/gnuplot.doc configure.in
