%%读取csv文件然后绘图
clc;
data = csvread('/home/lyb/tools/matlab/files/test.csv');
x = data(:,1);
y = data(:,2);
t = 1:size(x,1);

subplot(2,1,1);
plot(t,x,'r',t,y,'b');
% axis equal
% axis square
xlabel('time');
ylabel('value');
title('test csv read 1');

subplot(2,1,2);
plot(t, x+y, 'k');
% axis equal
xlabel('time');
ylabel('value');
title('test csv read 2');
set(gca,'linewidth',1,'fontsize',20,'fontname','Times');
legend('test')
