RE: Multiple mesh plot with a correct legend

[Xandri Farr]

Hi Ben

Thank you for the response.  I'm using GNU Octave, version 2.1.73.
I had a look at "help colormap" but this as far as I understand only
manages the colour of the different plots.  The part I would really
would like to edit is the description given to each mesh/surface 
drawn on the axis.  Something like "help legend" provides the following:

" Legend puts a legend on the current plot using the specified strings
  as labels. Use independant strings (@var{st1}, @var{st2}, @var{st3}...), a
  matrix of strings (@var{matstr}), or a cell array of strings (@var{cell})
  to specify legends. Legend works on line graphs, bar graphs, etc..."

I could not apply this command successfully to a multiple mesh plot. 

Your help will be appreciated.

Regards
Xandri

Can you tell us which version of Octave your are running?

In any event, take a look at "help colormap" ... does that do what you  
need?
