[Scilab-users] jetcolormap in param3d1

[Izabela Wójcik-Grząba]

Hi, 

In the meantime I've managed to achieve the main goal. An additional
problem appeared with my figure f2. Here is my function:

function colorplot(T, f2)

    t=diag(T);
    mt=size(t,'r');
    [sort_t,index_sort_t]=gsort(t,'g','i');

    f2.color_map=jetcolormap(mt);

    for i=1:mt
       
f2.children(1).children(7).children(mt-(index_sort_t(i)-1)).foreground=i;
    end

    colorbar(min(t),max(t),[1,mt]);
    f2.children(2).children(15).visible="off";

endfunction

Unfortunately the last line, which should switch off the visibility of a
group of polylines, doesn't work inside the function. When I put this
line in the console after calling function colorplot it works fine.
Maybe someone could help me with this?

Kind regards,
Iza
