Hi Daniel and list, sorry that it took me so long.
Here is a screenshot of the still to small markers (it was worse with the original octave version from ubuntu): http://www.fobg.de/wordpress/wp-content/uploads/2009/12/problem_example.png This is a screenshot of the changed version, marker size is 6 here: http://www.fobg.de/wordpress/wp-content/uploads/2009/12/demo_size6.png (I didn't do any change to the graphic driver - therefore it should be gnuplot) Attached is the diff file for my changes. Maybe someone could test it with some other config (Windows?)? Just use the "demo zplane" to have an example. If there are no objections I would check the changes in?
