From help-octave-request at bevo dot che dot wisc dot edu Tue Mar 30 12:26:35 2004 Subject: Problems with gnuplot 3.8k From: Joe Koski To: Octave_post Date: Tue, 30 Mar 2004 11:24:28 -0700 After installing octave-2.1.55 and octave-forge from the HPC web site on my Mac with OS X, I also installed gnuplot-3.8k.2, which I built from source. Octave and octave-forge seem to be working correctly. Thanks Guarav. The new gnuplot has "broken" all my multiframe plot sequences. This occurs both under X11 and aquaterm, so the problem is definitely within the new version of gnuplot, or at least within the octave-gnuplot interface. There are two problems. First, the subplot command is often ignored, and I get a full frame plot whether I want one or not. For example, my four frame plot quickly flashes three full page frames followed by the full frame of the last subplot that occurs just before a "pause." Sometimes it mixes full frames and subplots. As was mentioned to me, there seems to be a bit of voodoo involved in the programming to get things to work correctly. The second problem is with multiple axes on a plot frame, sometimes with multiple traces. Simple, full frame x-y plots seem to behave properly. Per sent me an example that eliminated some "gnuplotisms" in my coding and successfully fixed a relatively simple loop of three vertically spaced frames. In trying to replicate his results with four vertical frames, I keep running into the problems above, seemingly without logic. The purpose of this posting is two-fold. First, can anyone confirm that this is a general gnuplot-3.8k related problem? Is it also seen on Linux boxes? Second, if you are considering the switch to gnuplot-3.8k, think twice. To whom should I submit a bug report? Is it in the octave interface, gnuplot, or both? This means that I'm not quite ready to summarize an "easy" install route for Octave on Macs on a wiki site. We're close though, I hope. Joe Koski ------------------------------------------------------------- Octave is freely available under the terms of the GNU GPL.
