Version 2.0
-----------

Added support for tics options: xtics, ytics, ztics, x2tics, and y2tics. 

Added "Save Xgfe" and "Load Xgfe" items to "File" menu. "Save Xgfe" will save
all plotting information to a specially formatted text file so that "Load Xgfe"
will load the data and fill in the GUI with the data to re-create the plot. 

Corrected my misunderstanding of plot sizes. Plot sizes are always scaling 
factors. In the postscript and pbm terminal options, I filled in the default
sizes of 10x7 and 640x480 respectively. Gnuplot read these numbers as 
scaling factors. Changed to input sizes as 1 for scaling factors. 

Added dialog to specify box width for boxes style of plotting

Modified plot size dialog to load currently stored values. 

Modified latex, emtex, pbm, and postscript terminals to load currently
stored values. 

Added enhanced option to the postscript terminal 
(thanks to Chi-hsuan Lai for sending in a patch)

Changed terminal label to display terminal name only; will not include
options in label. 

Made sure all dialogs are keyboard friendly.

Added curve fitting support. 

Added geometry management to main dialog, and many other dialogs for the 
ability to resize windows with the mouse. 

Added Advanced Menu for multiple files, multiple functions, and curve fitting. 

Re-arranged Options menu to make more sense. 

Added support for index, every, and smooth datafile modifier commands. 

Added log-scale support

Added capability to call external programs for data file filtering

Added the following plotting styles for data files 
(for use with v3.6 of gnuplot): fsteps, histeps, xerrorbars, yerrorbars,
xyerrorbars, boxerrorbars, boxxyerrorbars, financebars, candlesticks

Added option for selecting bar size for use in bar type plots

Added multiple file/multiple function support. 

Version 1.2

selected for datafiles. 

Added support for all options relating to the legend or "key" as Gnuplot
