[Tioga-users] tioga 1.4

[Edwin]

Hi,

I'm curious to know if anyone else has problems with tioga-1.4?

The gem seems to install the libs wrongly. There is no directory Tioga  
under the libs, so when tioga.rb requires Tioga/FigureMaker it can't find  
it. The easiest way around it was to make the directory and copy  
everything in the lib dir to it.

Next I get an segmentation fault when trying to plot a plot:
edwin at vimes:~/documents/rhul/popdyn/article$ tioga popdyn_plots.rb -13
loading /home/edwin/documents/rhul/popdyn/article/popdyn_plots.rb
/usr/lib/ruby/site_ruby/1.8/Tioga/FigMkr.rb:897: [BUG] Segmentation fault
ruby 1.8.5 (2006-12-04) [i686-linux]

Aborted

The corresponding line in FigMkr.rb:
         show_axis(self.xaxis_loc) if self.xaxis_visible

(This happened with both the gem version and the other version).
I'm using gentoo linux, gcc 4.1.1.

On a more positive note, the new commandline tools seem to be very nice  
and thanks for providing a gem version, which makes installing and  
updating a lot easier. I'm also curious about the new arrow fixes, because  
I did have some problems with plotting vectorfields (when the arrowheads  
were scaled down they wouldn't attach to the tail anymore)
