[Scilab-users] Format legends of a graph as a 2D table

[CRETE Denis]

Thank you Samuel, this works great !
I added a frame around the whole table:

clf
nL = 40;   // number of Legends
Lpc = 15;  // number of Lines per column
names_legend = "legend_"+string(1:nL);
x = 0;
i = 1;
j = min([Lpc, nL]);
y0=[];
while i<=nL
//    disp(i)
    legends(names_legend(i:j), i:j, ..
        font_size=3, opt="ul");
    idL = gce();
    h=idL.children($);
    if i==1 then
        x0=h.data(1,1);
    end;
    y0=[y0;h.data(4,2)];
    move(idL, [x,0]);
    // width of this block
    w = strange(h.data(:,1));
    // masks the frame
    h.line_mode = "off";
    x = x+w; //position of next block
    i = i+Lpc;
    j = min([j+Lpc, nL]);
end;
h.data([1,4],1)=[x0;x0];
h.data([3,4],2)=min(y0)*ones(2,1);
h.fill_mode="off";
h.line_mode = "on";

I do not understand why it is not equivalent to refer to f1.children(1)  or to refer to a1 ...

Thank you for your help.

The following automatically splits nL legends if blocks of Lpc lines
(if there are parasitic line-wrapping when receiving this sample,
please correct them before running it. It is ok when sending it):

clf

nL = 40;   // number of Legends

Lpc = 15;  // number of Lines per column

names_legend = "legend_"+string(1:nL);

x = 0;

i = 1;

j = min([Lpc, nL]);

while i<=nL

    disp(i)

    legends(names_legend(i:j), i:j, font_size=3, opt="ul"<

 /span><

span style="color:rgb(74,85,219);">);

    idL = gce();

    move(idL, [x,0]);

    w = strange(idL.children($).data(:,1)); // width of this block

    idL.children($).line_mode = "off";  // masks the frame

    x = x+w;    // updates the position of next block

    i = i+Lpc;

    j = min([j+Lpc, nL]);

end
