stem3- different stem color and marker color for different values in an axis.

Hello all,

I have a following randomly generated stem3 plot. I wanted to know if there was any way we could assign different colors to markers corresponding different values in x-axis i,e x =1, 2,3,4 should have different colored markers?

Two options:

x = (ones(50,1)*(1:4))';                                        % Create Data
y = ones(size(x,1),1)*(1:50);                                   % Create Data
z = randi(99, size(x));                                         % Create Data
fc = jet(size(x,1));                                            % Choose Colormap

figure
hold all
for k = 1:size(x,1)
    stem3(x(k,:),  y(k,:), z(k,:), 'Color','b', 'MarkerFaceColor',fc(k,:))
end
hold off
grid on
view(-30,35)

figure
stem3(x(:), y(:), z(:))
hold on
scatter3(x(:), y(:), z(:), [], x(:), 'filled')
hold off
grid on
view(-30,35)

Experiment to get the result you want.
