Having trouble getting legend to display properly

So I'm basically trying to make 1 general legend for multiple subplots (they should all have same legend).

I know matlab doesn't let you change many of the features of the legend (spacing, etc.) so I've opted to make a 4x4 subplot but only plot my figures in the first three columns and reserve the last column for my legend.

Here is my code:

% to plot all individuals across trials in subplot
odortrial = 3;
trialn = 6;
G = figure
B = (1:1:odortrial)
tri = (1:1:trialn).';

% for plotting only in first 3 cols
A = 1:1:numel(d)
A(mod(A,4)==0) = nan;
CC = A(~isnan(A));
ind = CC.';
num = [num2str(tri)];
for ii = 3:length(d)
    for t = 1:trialn
    if d(ii).isdir == 1
        Gsub(i) = subplot(row,col,ind(ii-3));
        L(t) = plot(B, Q{ii,1}(t,:), 'DisplayName', num);
        ylim([0,10]);
        hold on
        title(sprintf('Fly %s%d', d(ii).name));
    end
end
end

% subplot(row,col,1)
% plot(B,Q{4,1}(1,:))

A = zeros(size(numel(d)));
for i = 3:length(d);
    if d(i).isdir == 1 ;
    A(:,i) = d(i).isdir;
    end
end

leg = legend(gca,'show');
% leg.FontSize = 6;
title(leg,'Trial #');
            hold on
            
newPosition =  get(subplot(row,col,4),'Position')
% newPosition(2) = newPosition(2)*2
newUnits = 'normalized';
set(leg,'Position', newPosition);

What I end up with is a legend that is covered by a blank subplot. How can I get rid of this? (Looks like this).

One possibility is to set the 'Visible' property of those axes to 'off'. Here is a simpler example ...

figure
plot(magic(3))
legend
set(gca,'Visible','off')

You could also try putting a common legend on the bottom of the page. Here is an example of how to do that

x = 1:100;
y = rand(100,6,9);
tri = (1:1:trialn).';
fig = figure
ax = gca
for k = 1:size(y,3)
    subplot(3,3,k)
    plot(x,y(:,:,k))
end
% add a common legend
h = legend(num2str(tri),'Orientation','horizontal');

% relocate it to bottom of plot
p = get(h,'Position');

p(1) = 0.2; % normalized x position
p(2) = 0.005; % normalized y position
set(h,'Position',p,'Units','normalized')

Sorry the image of the plot looks a little wonky, but it should look OK on your screen.
