I checked in the following change to fix this problem.

If you always want soild lines, you can add "-solid" to the options
for the print command.

I don't see how to control dashed/solid properties for individual
lines with gnuplot.

        * plot/__uiobject_draw_axes__.m: Use title "" if no explicit title.
        When setting {x,y,z}lim, also set {x,y,z}limmode to "auto.
