Matlab读取yolov3训练的多个txt文件数据并绘图
最近用yolov3训练自己的数据，使用三种预训练权重，生成了三个txt文件数据，数据格式如下：
首先将三个txt文件复制到matlab bin目录下，将数据导入到matlab中，在工作区会看到导入的数据。绘图代码如下
`data1 = load(‘noweights.txt’);
data2 = load(‘darknet53.txt’); % data1,2,3 加载txt文件
data3 = load(‘spp.txt’);
save(‘data1.mat’,‘data1’);save(‘data2.mat’,‘data2’);save(‘data3.mat’,‘data3’); %将txt保存为.mat格式
figure(1);
x = data1(:,1); %读取第一列数据
c1 = data1(:,3);
c2 = data2(:,3); % 读取第三列数据
c3 = data3(:,3);
subplot(251);
plot(x,c1,‘r:’);title(‘GIoU’);xlabel(‘epochs’);ylabel(‘loss’);hold on;
plot(x,c2,‘b–’);hold on;
plot(x,c3,‘g’);
figure(1);
x = data1(:,1);
c1 = data1(:,4);
c2 = data2(:,4);
c3 = data3(:,4);
subplot(252);
plot(x,c1,‘r:’);title(‘Objectness’);xlabel(‘epochs’);ylabel(‘loss’);hold on;
plot(x,c2,‘b–’);hold on;
plot(x,c3,‘g’);

x = data1(:,1);
c1 = data1(:,14);

c3 = data3(:,14);
subplot(257);
plot(x,c1,‘r:’);title(‘val Objectness’);xlabel(‘epochs’);ylabel(‘loss’);hold on;
plot(x,c2,‘b–’);hold on;
plot(x,c3,‘g’);

plot(x,c1,‘r:’);title(‘F1’);xlabel(‘epochs’);ylabel(‘loss’);hold on;
plot(x,c2,‘b–’);hold on;
plot(x,c3,‘g’);`
绘制结果如下
绘制完后可以点击下图中位置，对坐标轴信息进行编辑
