Problem with version 4.4?

Show all headers | View raw

I am a beginner with gnuplot.  I have a (fortran) program that was 
written several years ago that creates a gnuplot input file.  I am now 
running version 4.4 of gnuplot on MacOSX 10.6.7 (64-bit kernel) and some 
of these input files no longer work.

The command that is broken draws a set of red and green filled circles.  
Here is a short example of one of the circles that no longer works:

gnuplot> plot [t=-pi:pi]    .1250*cos(t)+3.0000,.3280*sin(t)+0.0000 with 
filledcurve 2
                                                                                     
^
         ';' expected

That line may wrap in the newsgroup posting, but hopefully you can see 
what it does.  The "filledcurve 2" part of the command is supposed to be 
green.  As near as I can tell, there is really no missing ';' in that 
commend.  It simply does not accept the color specification.

I'm using the Aqua terminal type, but I have tried also xterm and svg 
terminals, and I get the same error.  So I don't think this is related 
to the terminal type.

Is this a problem with my version of gnuplot, or is this some kind of 
obsolete syntax that has been replaced, or what?  My gnuplot is compiled 
with the fink package manager, and this is the latest supported fink 
version.  Here is the version info:

gnuplot> show version

        G N U P L O T
        Version 4.4 patchlevel 0
        last modified March 2010
        System: Darwin 10.7.0


Any help would be appreciated.
