URL: <http://savannah.gnu.org/bugs/?38943> Summary: Extremely poor plotting performance with gnuplot Project: GNU Octave Submitted by: None Submitted on: Wed 08 May 2013 09:50:42 PM UTC Category: Plotting Severity: 3 - Normal Priority: 5 - Normal Item Group: None Status: None Assigned to: None Originator Name: Originator Email: address@hidden Open/Closed: Open Discussion Lock: Any Release: 3.6.3 Operating System: GNU/Linux _______________________________________________________ Details: I was trying to run the following matlab script: http://www.mathworks.de/matlabcentral/fileexchange/35355-stability-chart (The script needs to be unpacked, after that just enter "StabilityChart;" in octave) The problem is that the execution using octave takes a very long time; it is slower than matlab by a factor of at least 100. The profiling shows that the lion share of the execution time is being spent in the __go_line__ function. The execution time decreased to something comparable to matlab once I removed all of the plot commands from the script. I would appreciate it if you could look into this problem :) _______________________________________________________ Reply to this item at: <http://savannah.gnu.org/bugs/?38943> _______________________________________________ Message sent via/by Savannah http://savannah.gnu.org/
