Hi all,

I am using gnuplot 4.6 patchlevel 0 and having trouble with polar graphs. There always seems to be a black line drawn at 0-degrees.

You can see this on the polar demos page in any of the demo plots:
http://gnuplot.sourceforge.net/demo/polar.html

Demos for older versions do not seem to show this line:
http://gnuplot.sourceforge.net/demo_4.4/polar.html

I have searched for others seeing this problem for the last day but haven't found any reference to the issue.
I have tested this with pdf, postscript, cairopng and svg and seen the same behaviour in all.

Does anyone know what this line is and how it can be removed, for example from any of the polar demos?

Thank you,
Daniel
