[Scilab-users] bode plot

[Paul Bignier]

Hi Raghu,

You need to retrieve the axes of the second plot thanks to the children 
of gcf().

Here is how I did it, based on your snippet:

function set_gr_txt(fnt_sz)
     // sets textize in plots to larger (4)
//    [out, inp] = argn(0);
//    //if inp < 1 then, x = 1, end //set default font size to 1

     f = gcf();

     a1 = f.children(1);
     if ~exists("fnt_sz","local") then // default size
         fnt_sz = 4;
     end
     a1.font_size = 4; // axis font size
     x_label=a1.x_label;
     x_label.font_size=fnt_sz;
     y_label=a1.y_label;
     y_label.font_size=fnt_sz;
     t = a1.title;
     t.font_size=fnt_sz;
     //disp(is_handle_valid(a1),typeof(h),'typeof handle');

     a2 = f.children(2);
     if ~exists("fnt_sz","local") then // default size
         fnt_sz = 4;
     end
     a2.font_size = 4; // axis font size
     x_label=a2.x_label;
     x_label.font_size=fnt_sz;
     y_label=a2.y_label;
     y_label.font_size=fnt_sz;
     t = a2.title;
     t.font_size=fnt_sz;
     //disp(is_handle_valid(a2),typeof(h),'typeof handle');

endfunction

// Execution:
bode()
set_gr_txt(4)

Regards,
Paul
