How to plot multi data set in matlab?

Hello, I am facing a problem with plotting the graph. I wish to plot the graph in the iteration as for loop is using in my coding. I had a data set,a with 8 variables, which made to 300x8 matrix, while another set of data,w is 1x8 matrix and w is updating for every iteration. But sometimes the w may update or increase more than 1 row in the coding. I just want to plot the a and w for every iteration in same plot. Can the w that changes for every iteration plot as line graph. Here is my full coding, maybe can have a look. When I run the code, it encounter error that the matrix length is different. I wish to run it in live script because need to record video. Thank you.
clc
index=0;
load ('S1.mat')
load ('var.dat','-mat');
learning_rate=0.001;
data_size=size(Untitled);
for i=1:data_size(1)%%indicating size of matrix S1 row
current_reading=Untitled(i,:);
index=index+1;
neuron_matrix_size=size(w);
for j=1:neuron_matrix_size(1)%%indicating size of matrix w row
for k=1:neuron_matrix_size(2)%%indicating size of matrix w column
square_distance=((current_reading(k)-w(j,k)).^2);
end
euc_distance_neuronj=sqrt(square_distance);
if j==1
euc_distance = [euc_distance_neuronj];%%this is the first time create this matrix
else
euc_distance = [euc_distance euc_distance_neuronj];%%this is when the matrix has been created
end
end
%%find the best matching neuron and determine which neuron win
[minimum_distance,winning_neuron] = min(euc_distance);
%%disp(euc_distance,'euc_distance')
%%disp(minimum_distance,'minimum_distance = ')
if minimum_distance<0.05
h(winning_neuron)=h(winning_neuron)+1;
%%update weight
for k=1:neuron_matrix_size(1)
w(k,winning_neuron)=w(k,winning_neuron)+learning_rate*(current_reading(k)-w(j,k));
end
else
%%disp(w,sensor_reading)
h = [h 1];
w = [w;current_reading];
end
plot(i,Untitled);
hold on;
plot(i,w);
end
