close all;
clc;clear;

filename1 = '1.txt';
filename2 = '2.txt';
data = load(filename1);
datat = load(filename2);

data1 = data(:,1);
data2 = data(:,2);

datat1 = datat(:,1);
datat2 = datat(:,2);

figure();
plot(data1,data2,'k','LineWidth',2);
title('testTitle','fontname','Times New Roman','Color','k','FontSize',12);
xlabel('x[m]','fontname','Times New Roman','Color','k','FontSize',12);
ylabel('y[m]','fontname','Times New Roman','Color','k','FontSize',12);

hold on;
plot(datat1,datat2,'--r','LineWidth',2);
legend('1','2',1);
set(gca,'FontName','Times New Roman','FontSize',12);

结果示意：
