Hello, some of you may have seen it over in the user list/newsgroup, but I think this should be addressed here, too: A user just found a problem with gnuplot-3.8 that has been sitting in there for quite some time now: contour lines are now drawn as individual line segments, where 3.7 managed to long polylines (sometimes *too* long, leading to its own kind of problems). That's bad if the line type used is patterned, because individual segments re-start the pattern each time, rendering the pattern indecipherable. The key difference is in graph3d.c:cntr3d_lines() and friends: in 3.7, they used clip_move() and clip_vector() to create (optionally clipped/broken) polylines. In 3.8, we use draw3d_line directly, which does both a term->move() and term->vector(), usually. AFAICS, it was me who did that, as part of the big set of modifications done on the "axis branch". I guess this will have to be fixed, too, before a 4.0 becomes ready. Looks like I just found something to do for the holy days. -- Hans-Bernhard Broeker (br...@ph...)
