multiaxes and tiles inside a loop, how to plot different values for each tile independently

In the following code I will like to ask the following questions:

1. How can I plot a horizontal line of 0.3 in zone 1 and another horizontal line value in zone 2 and different for zone 3 and zone 4
2. How can I center the x axis label
3. How can this code be enhanced
4. I am having trouble with x labes and y labels and tick marks. How can I label each y axis independendently.

Thank you

C_p_max_single_Tap=[0.45,0.383,0.513,1.683,1.494];
clear all; %get rid of everything in memory
close all; %close all open figures

C_p_max_single_Tap= [0.450,0.383,0.513,1.683,1.494];
C_p_max_single_Tap=round(C_p_max_single_Tap,3)

C_p_max_single_Tap = 1×5

0.4500 0.3830 0.5130 1.6830 1.4940

t=tiledlayout(1,5,'TileSpacing','none');

        [0 0 1], 'MarkerSize', 14)
    hold on
    yline(0.3,'--','LineWidth',3, 'Color', [0.9, 0.2, 0.2]);

Here are answers to each of your questions

Q1: How can I plot a horizontal line of 0.3 in zone 1 and another horizontal line value in zone 2 and different for zone 3 and zone 4?

In your for loop, you're calling yline with 0.3 on each axes, if you want to call it with a different value for each axes, make a vector at the beginning and call it with those values:

ylinevals=[0.3 0.4 0.2 0.5 0.1];
...
    for i = 1:5
        ...
        yline(ylinevals(i),...)

Q2: How can I center the x axis label?

The x axis label is currently centered...but on the 5th axes. the function xlabel uses the current axes as a target by default. Instead, set the label of the tiledlayout:

xlabel(t, ...)

Q3: How can this code be enhanced ?

(I think you need to be more specific here)

Q4: I am having trouble with x labes and y labels and tick marks. How can I label each y axis independendently.

You can set them in your loop, using ylabel (taking the strategy as above)

mylabels=["a" "b" "c" "d" "e"];
...
for i = 1:5
    ...
    ylabel(mylabels(i))
    

You can set them after by specifying a target for ylabel (using nexttile helps here)

...
end
% set(t.Children(1:4), 'ylabel', []) % OMIT this line of code either way
ylabel(nexttile(1),"Label for left-most axes")
ylabel(nexttile(2),"Label for second axes")
...
    

If you want to keep the y tick labels, omit the line where you remove them.
