How to plot a mean value as a function of specific value pairs ?

How can I plot the following data in a nice plot?

a=[ [1 2], [2 3], [4 5] ]; mean= [ 5.43, 6.78, 5.66];

Thank you

The phrase "a nice plot" has no real meaning, except to you. What kind of plot would you wish to see? Does your plot live in two dimensions? In three dimensions? Explain what it looks like as you want to see it.

There is no difference between a=[ [1 2], [2 3], [4 5] ] and a=[ 1,2,2,3,4,5]. Is there a reason for this complicated notation?

Is this nice?

X=[1,2,4];
Y=[2,3,5];
Z=[5.43,6.78,5.66];
plot3(X,Y,Z,'*');
grid on;

@Avam Al-Saffar: Type this in the command window:

a = [[1 2], [2 3], [4 5]]
b = [1,2,2,3,4,5]
isequal(a, b)   % replies TRUE

Both are exactly the same.

@Massimo: Please post your solution as answer, such that it can be accepted to mark this thread as solved. Thanks.

@Jan Simon: Yes, it is and sorry about that. I wanted to say that I have a two species with different initial conditions so they are x=[1,2,4] and y=[2,3,5].

First, notice that in Matlab a=[ [1 2], [2 3], [4 5] ] equals a=[1,2,2,3,4,5]. I guess, you meant to associate each entry of mean=[5.43, 6.78, 5.66] with one coordinate couple (x,y) in a.

To do that, just define your X and Y and plot mean against them:

X=[1,2,4];
Y=[2,3,5];
mean=[5.43,6.78,5.66];
plot3(X,Y,mean,'*');
grid on;
