Hi,

Is it possible to produce grid lines in a Tioga plot? I've looked  
through the examples and documentation and was unable to any mention  
of grid lines.

Thanks.

Ivars

Message-ID: <af5291a30704120131y97663dak5676a6791976155f@mail.gmail.com>

Hello !

I have loved the routine

@x.each2(@y) do |x,y| ... end

to progress into 2 dvectors simultaneously, but unfortunately, I do
most of my work (when using dvectors outside of Tioga) with 3
dimensions or more so I wonder if it would be possible to implement an
each_many routine that could be used as

@x.each_many(@y, at z, at t, at u, at v, at w) do |x,y,z,t,u,v,w| ... end

and which determines automaticaly how many Dvectors to use from the
number of arguments.

For the moment, I get along with indexes but it's less convenient in writing.

Cheers,

JJ

You can add this capability yourself, by augmenting the Dvector class as  
follows:

module Dobjects
   class Dvector
     def each_many( *vectors, &block )
        self.each_index do |i|
          args = Array.new
          vectors.each { |v| args.push( v[i] )  }
          block.call( self[i], *args )
       end
     end
   end
end

Example:

require 'Dobjects/Dvector'
include Dobjects
module Dobjects
   class Dvector
     def each_many( *vectors, &block )
        self.each_index do |i|
          args = Array.new
          vectors.each { |v| args.push( v[i] )  }
          block.call( self[i], *args )
       end
     end
   end
end

v1 = Dvector[1,2]
v2 = Dvector[3,4]
v3 = Dvector[5,6]
v1.each_many(v2,v3) { |x,y,z| p x+y+z }
=> 9.0
=> 12.0

Hi Ivars,

There isn't anything special for grid lines in Tioga (at least not  
yet!), but you can
do-it-yourself pretty easily.  Here's the "Blues Plot" from samples/ 
plots.rb with
grid lines added by hand.

     def blues_with_grid
         read_data
         t.do_box_labels('Blues Plot', 'Position', '\textcolor[rgb] 
{0,0,1}{Blues}')
         show_model_number
         xs = @positions
         ys = @blues
         t.show_plot(plot_boundaries(xs,ys, at margin,-1,1)) {
             t.context {
                t.line_width = 0.5
                t.line_type = Line_Type_Dot
                t.line_color = Gray
                [0,2,4,6].each {|x| t.stroke_line 
(x,t.bounds_top,x,t.bounds_bottom) }
                [-1,-0.5,0,0.5,1].each {|y| t.stroke_line 
(t.bounds_left,y,t.bounds_right,y) }
             }
             t.show_polyline(xs,ys,Blue) }
     end

Thanks for the trick Edwin, I'll do this.
