In order to combine the three graphs in a unique figure you could use subplot.
figure
% First set of data
subplot(1,3,1)
plot(x_graph1, y_graph1, 'color', 'b')
title('Data of code 1')
% Second set of data
subplot(1,3,2)
plot(x_graph2, y_graph2, 'color', 'r')
title('Data of code 2')
% Third set of data
subplot(1,3,3)
plot(x_graph3, y_graph3, 'color', 'g')
title('Data of code 3')
Or if you just want the three data sets in a unique graph you could just:
figure
plot(x_graph1, y_graph1, 'color', 'b')
hold on
plot(x_graph2, y_graph2, 'color', 'r')
hold on
plot(x_graph3, y_graph3, 'color', 'g')

To load the saved data sets in your workspace you should:
data1=load('filename1.mat');
data2=load('filename2.mat');
data3=load('filename3.mat');
Then execute the code I suggested but changing the x_graph to data(:,1) and y_graph to data(:,2) for each data set plot. e.g.
figure
plot(data1(:,1),data1(:,2),'r')
hold on
plot(data2(:,1),data2(:,2),'b')
hold on
plot(data3(:,1),data3(:,2),'g')
title('Results of 3 datasets')
