Defining scatter plot with different 'markers' & 'colors'

2 views (last 30 days)
Hi i am plotting a 3D scatter plot however i have to mark all 12 different classes on the 4th colomun in the attached file with 12 different markers and colors. Is there a way to randomize the 12 colors and markers all do i have to define them one by one? l only know how to do up till the 3d plot. Thanks in advance! :)
function plot3Ddata(x,y,z)
test = xlsread('HQ3.xlsx', 'A2:C223');
x=test(:,1);
y=test(:,2);
z=test(:,3);
scatter3(x,y,z);
end
the above code is my code for now...

This should be close to what you need:
test = xlsread('HQ3.xlsx', 'A2:D223');
x=test(:,1);
y=test(:,2);
z=test(:,3);
groups=test(:,4);
figure(1),clf(1)
for g=1:max(groups)
L=groups==g;
scatter3(x(L),y(L),z(L),...
'DisplayName',sprintf('group %d',g));
hold on
end
hold off

Hi so sorry for the late response, but is there a possibility to make all of them with different shapes and colors as i wan to distinctively reseperate them for better visualisation. Thanks alot for the follow up, really appreciate it! :)

If you don't want circles you can use plot3 instead of scatter3. Then you can set the LineSpec to whatever spec you like.
