i have
Z1={{rand(1,3)},[{rand(1,3)} {rand(1,3)} {rand(1,3)} {rand(1,3)} {rand(1,3)} {rand(1,3)} {rand(1,3)}],[{rand(1,3)} {rand(1,3)} ] }
cl='gbrcmykw';
for k4=1:numel(Z1)
y=cell2mat(Z1{k4}');
plot3(y(:,1),y(:,2),y(:,3),[ cl(k4) 's'],'MarkerSize',12,'DisplayName',sprintf('Zhluk %k4',y))
hold on
end
title('Priebeh zhlukovania','FontSize',16,'Color','k')
legend('show','Location','NorthEastOutside')
hold on
and i have
TAZ4=[ 1 2 7; 1 2 8; 1 2 3; 7 4 1; 4 5 6 ]
for k4=1:size(TAZ4,1)
plot3(TAZ4(k4,1),TAZ4(k4,2),TAZ4(k4,3),[cl(k4)'X'],'MarkerSize',10,'DisplayName',sprintf('Tazisko %k4',TAZ))
hold on
end
legend('show','Location','SouthEastOutside')
How do I add two legends to a single plot ?
Thanks.

I'm not really sure that code does what you think it does... you're looping over the points too many times in your drawT function (I don't think you want that outer loop, just a single i to use if your if cases. Also, %k isn't a valid sprintf format, so you're labels are all the same.
Anyway, here's a simplified version... you can build from there.
MON = [2.8 3.6 17.2; 5.4 8.3 15.8; 2.5 3.2 17.6];
Z1={{rand(1,3)},[{rand(1,3)} {rand(1,3)} {rand(1,3)} {rand(1,3)} {rand(1,3)} {rand(1,3)} {rand(1,3)}],[{rand(1,3)} {rand(1,3)} ] }
cl='grbckmyw';
axes('position', [0.1 0.1 0.7 0.8]);
view(3);
hold on;
for ii = 1:size(MON,1)
h1(ii) = plot3(MON(ii,1), MON(ii,2), MON(ii,3), ...
'marker', 'X', ...
'color', cl(ii), ...
'displayname', sprintf('Tazisko %d', ii), ...
'MarkerSize', 10, ...
'linestyle', 'none');
end
cl='gbrcmykw';
for ii = 1:size(Z1,2)
xyz = cat(1, Z1{ii}{:});
h2(ii) = plot3(xyz(:,1), xyz(:,2), xyz(:,3), ...
'marker', 's', ...
'color', cl(ii), ...
'displayname', sprintf('Zhluk %d', ii), ...
'markersize', 10, ...
'linestyle', 'none');
end
leg1 = legendflex(h1, get(h1, 'DisplayName'), 'anchor', {'ne','nw'}, 'buffer', [5 0]);
leg2 = legendflex(h2, get(h2, 'DisplayName'), 'anchor', {'se','sw'}, 'buffer', [5 0]);

You can't have two legends associated with a single axis using Matlab's legend. However, you can with legendflex. Remove your legend calls and add this code to the end:
pos = get(gca, 'position');
set(gca, 'position', pos.*[1 1 0.8 1]);
h1 = findall(gca, 'marker', 's');
h2 = findall(gca, 'marker', 'X');
leg1 = legendflex(h1, get(h1, 'DisplayName'), 'anchor', {'ne','nw'}, 'buffer', [5 0]);
leg2 = legendflex(h2, get(h2, 'DisplayName'), 'anchor', {'se','sw'}, 'buffer', [5 0]);
You could make all this plotting a lot cleaner if you saved the handles of your plot objects, and then set things like marker and color after the fact, but I've left that alone for now. Note that I added the resizing of the axis, since unlike legend, legendflex doesn't automatically resize axes to allow space for legends.
