Hey guys,
I have 4 vectors HQ10, HQ100,HQ1000,HQ10000
for example: HQ10 =[1 1.5 1.7 1.6 1.8 2.1 2.2 2.5]
HQ100 = [1.9 2 2.2 2.5 2.7 2.9 3 3.1]
I want to plot them like in the figure attached where the x axes (HQ10 HQ100 HQ1000 HQ10000), and y axes represents the values.
I want the first value of all the vectors be the same colour, the second values be the same colour, and so on..
I hope I made my question clear because it is a little bit difficult to explain
would welcome any help or suggestions
thanks in advanced!

Use plot
clc,clear
HQ10 = [1 1.5 1.7 1.6 1.8 2.1 2.2 2.5];
HQ100 = [1.9 2 2.2 2.5 2.7 2.9 3 3.1];
HQ1000 = rand(1,length(HQ10))*3;
cmap = jet(8); % color data
x1 = [-1 1]*0.1; % line length
hold on
for i = 1:length(HQ10)
h(1) = plot(x1+1,HQ10(i)+x1*0);
h(2) = plot(x1+2,HQ100(i)+x1*0);
h(3) = plot(x1+3,HQ1000(i)+x1*0);
set(h,'color',cmap(i,:))
set(h,'linewidth',3)
end
hold off

Thank you very much! that what I was looking for.
Do you know how I can ledgend by the colour?
for example the blue line represents 1900 , light bule represent 1800, green represents 1700

h = zeros(length(HQ10),3);
hold on
for i = 1:length(HQ10)
h(i,1) = plot(x1+1,HQ10(i)+x1*0);
h(i,2) = plot(x1+2,HQ100(i)+x1*0);
h(i,3) = plot(x1+3,HQ1000(i)+x1*0);
set(h(i,:),'color',cmap(i,:))
end
set(h,'linewidth',3)
legend(h(:,1),'blue', ...
'blue1', ...
'cyan', ...
'green', ...
'yellow')

do you mean like this ?
HQ10 =[1 1.5 1.7 1.6 1.8 2.1 2.2 2.5]
HQ100 = [1.9 2 2.2 2.5 2.7 2.9 3 3.1]
plot(HQ10,'red');
hold on;
plot(HQ100 ,'blue');
legend('HQ10','HQ100')

no, I mean in the same way as in the image I have attached.
every first value of the vectores represents a time period. this is way I want to plot the first values at the same coluor, then the second values at another colour..
I dont really know what type of plotting that is. tried to search the answers here but couldnt see some thing similar.
