Okay, so I'm just starting to look at this. First function to look at is 
'plot'...

1) The help text claims that (as an example) 'plot(10, 10)' will plot a 
single point. Currently this isn't true. Instead a zero-length (and 
hence non-visible) line is drawn. Is this a bug in the help text or the 
code?

2) The current help text doesn't mention the "--", ":", and "-." line 
styles. The code doesn't complain about any of these line styles, but it 
draws solid lines (and not dashed ones). Should these line styles still 
be documented?

3) The "<" and ">" marker styles doesn't produce triangles that point to 
the left or right, but instead they point up or down. Is this a 
limitation of gnuplot? Anyway, should these marker styles be documented?

4) The "p" (pentagon) and "h" (hexagon) marker styles produces squares 
and diamonds. I seem to remember gnuplot having a "house" marker style 
that could be used for pentagon. Anyway, should these marker styles be 
documented?

5) The "@nm" style doesn't work for me. I can only change the color of 
the marker this way. The marker style is always "+". Is this a bug, or 
has that feature been deprecated? Should the "@nm" style still be 
documented or is too gnuplot specific?

Thanks,
Søren
