Setting line colour between two matrix plots on the same graph

Hi everyone, so I'm sure there is a simple answer to this but I can't quite figure it out. Say I have two 4x4 matracies, X and Y that I want to plot on the same graph against the same variable Z, I am currently doing something like this:

plot (X,Z,'.')
hold on
plot (Y,Z,'*')
title ({title})
legend ('X','Y')

I am wanting the colour of the plots X and Y to match up for different Z values. So for example, X(:,1) and Y(:,1) are both red, X(:,2) and Y(:,2) both green etc...

I hope that explenation makes sense, any help would be very much appreciated. I know I could use a for loop to just plot the columns individually and then set the colour but I thought there may be a much quicker way?

Thanks,

Will

You just need to reset the color order index every time you start the colors from the beginning

X = [1 2 3 4; 1 2 3 4; 1 2 3 4; 1 2 3 4]';
Y = [1 2 3 4; 1 2 3 4; 1 2 3 4; 1 2 3 4]'+4;
Z = [1 2 3 4; 1 2 3 4; 1 2 3 4; 1 2 3 4]'+(1:4);

ax = axes();
plot (X,Z,'.')
hold on
ax.ColorOrderIndex = 1; % <--- reset the ColorOrderIndex to 1
plot (Y,Z,'*')

Thank you, that worked perfectly!
