How to write a For loop for the last characters vector names

I have the following variables that I want to plot:

t=1:1:20
P_eA 
P_eZ 
C_eA  
C_eZ

I can make a subplot by writing

figure(1) 
subplot(2,1,1)
plot(t, P_eA)
subplot(2,1,2)
plot(t, C_eA)

figure(2) 
subplot(2,1,1)
plot(t , P_eZ)
subplot(2,1,2)
plot(t, C_eZ)

However, I'm wondering if there is a way to write a for loop where I can loop over the last characters of each vector. What I am thinking of is something like

char = char('eA','eZ');

for i=1:2
    figure(i)
    subplot(2,1,1)
    plot(t, P_{char(i,:)})
    subplot(2,1,2)
    plot(t, C_{char(i,:)})
    end
end

Example: You could also use a table () for this. https://www.mathworks.com/help/matlab/matlab_prog/generate-field-names-from-variables.html. Note: Naming a variable char is a terrible idea!!

clear all
t=1:1:20
P.eA = rand(1,20)
P.eZ = rand(1,20)
C.eA = rand(1,20)
C.eZ = rand(1,20)
P_names =fieldnames(P)
C_names =fieldnames(C)
for k = 1:numel(P_names)
    figure(k)
    subplot(2,1,1)
    plot(t, P.(P_names{k}))
    subplot(2,1,2)
    plot(t, C.(C_names{k}))
end
