Octave Forge functions in 3.0.0

[P.J.G. Long]

  I apologies if I have missed a previous post, but I am having problems 
getting our installation of 3.0.0 to work as our 2.1.73 version.

The most obvious problem is related to some of the plotting functions we 
have been using, e.g. multiplot, legend and __gnuplot_raw__. Everything was 
working in 2.1.73, we then upgraded to 2.9.9 and I managed to mod the code 
to accept everything, with no errors/warnings, but with some issues of 
double printing the legend when plotting multiple datasets.

In the move to 3.0.0 the legend issue seems to have disappeared, but we now 
get multiple warnings re the use of __gnuplot_raw__ / __gnuplot_set__ to 
the point that I don't seem to be able to redirect the output to a .svg 
file as before, I am getting zero length files although the file is 
created. I addition, multiplot, which I assume comes from the octave-grace 
set of packages doesn't seem to work correctly, but this may be due to some 
dependancies. Is there a predefined method to installing the same packages 
as in 2.1.73 with a single command or does each package need to be 
'installed' manually?

    Thank you for any help
