Matlab代码片

1、论文、实验报告画图，xxx对比曲线

新建一个data.txt文件，拷贝进去下面数据

57.2  58.3  31     51.3
58.3  57.8  32.5  49
59.1  58    32.5  50.3
61.3  58.9  31.9  51.2
59.2  57.6  33.8  49.3 
61.0  57.4  33.5  48.5
60.1  57.6  32.1  52.6
57.2  58.3  35.3  52

x = 1:1:8;
data = importdata('data.txt');
data0 = data(:,1);
data1 = data(:,2);
data2 = data(:,3);
data3 = data(:,4);

figure()
plot(x, data0, "--mo"); hold on 
plot(x, data1, ":gs", 'LineWidth',1); hold on
plot(x, data2, "-.r+"); hold on
plot(x, data3, "-.k^"); hold off
xlabel("实验组别")
ylabel("温度(℃)")
legend('芯片1','芯片2','芯片3', '芯片4')
