Okay, so I'm just starting to look at this. First function to look at is 'plot'...On 27-May-2007, Søren Hauberg wrote:| 2) How much can I trust the help text of the functions? Have they been | updated when the graphics handles was introduced?Since things have changed so much with plotting, I think whatever is in the help text now should be verified.
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
