Hello everyone,
I have this code and I would like to individually change the colours of some points on the graph. How can I do this manually?
Thanks

scatter() and gscatter() give you some control over single marker colors.
Alternatively, you can using indexing to plot groups of coordinates that should have different colors.

You can simplify the code:
L = [0.974,1.366,9
0.929,1.321,11
0.848643,1.240643,14
0.779,1.171,18
0.718063,1.110063,22
0.664294,1.056294,26
0.616500,1.008500,28
0.573737,0.965737,29
0.535250,0.927250,28
0.500429,0.892429,26
0.468773,0.860773,22
0.439870,0.831870,18
0.413375,0.805375,14
0.389,0.781,11
0.3665,0.7585,8
0.345667,0.737667,5] ;
N = size(L,1) ;
x = cell(N,1) ;
for i = 1:N
x{i} = linspace(L(i,1),L(i,2),L(i,3)) ;
end
figure
hold on
for i = 1:N
plot(x{i},zeros(size(x{i})),'o','MarkerEdgeColor',[0 0 1],...
'MarkerFaceColor',rand(1,3),...
'LineWidth',1, 'MarkerSize', 10)
end
scatter(0,1.7,2000,'filled','MarkerEdgeColor',[0 0 1],...
'MarkerFaceColor',rand(1,3),...
'LineWidth',1.5)
text(0,1.7,'1.7m','HorizontalAlignment','Center');
xlabel('Distance (m)')
ylabel('Height (m)')
Also read about gscatter. Associate a value to each x{1} and use gscatter.
