Matlab中plot画图线型、标记和颜色

一、颜色

举例说明

x = 0:pi/100:2*pi;
y1 = sin(x);
y2 = sin(x-0.25);
y3 = sin(x-0.5);
y4 =sin(x-0.75);
y5 = sin(x-1);
y6 = sin(x-1.25);
y7 = sin(x-1.5);
y8 =sin(x-1.75);
figure
plot(x,y1,'y');%
hold on;
plot(x,y2,'m');%
hold on;
plot(x,y3,'c');%
hold on;
plot(x,y4,'r');%
hold on;
plot(x,y5,'g');%
hold on;
plot(x,y6,'b');%
hold on;
plot(x,y7,'w');%
hold on;
plot(x,y8,'k');%
hold on;

二、线型

举例说明

x = 0:pi/100:2*pi;
y1 = sin(x);
y2 = sin(x-0.25);
y3 = sin(x-0.5);
y4 =sin(x-0.75);
figure
plot(x,y1,x,y2,'--',x,y3,':',x,y4,'-.')

三、标记

举例说明

x = 0:pi/100:2*pi;
y1 = sin(x);
y2 = sin(x-0.25);
y3 = sin(x-0.5);
y4 =sin(x-0.75);
y5 = sin(x-1);
y6 = sin(x-1.25);
y7 = sin(x-1.5);
y8 =sin(x-1.75);
y9 =sin(x-0.75);
y10 = sin(x-2);
y11 = sin(x-2.25);
y12 = sin(x-2.5);
y13 =sin(x-2.75);
figure
plot(x,y1,'-o','MarkerIndices',1:5:length(y1));%创建一个线图并每隔四个数据点显示一个标记
hold on;
plot(x,y2,'-+','MarkerIndices',1:5:length(y2));%创建一个线图并每隔四个数据点显示一个标记
hold on;
plot(x,y3,'-*','MarkerIndices',1:5:length(y3));%创建一个线图并每隔四个数据点显示一个标记
hold on;
plot(x,y4,'-.','MarkerIndices',1:5:length(y4));%创建一个线图并每隔四个数据点显示一个标记
hold on;
plot(x,y5,'-x','MarkerIndices',1:5:length(y5));%创建一个线图并每隔四个数据点显示一个标记
hold on;
plot(x,y6,'-s','MarkerIndices',1:5:length(y6));%创建一个线图并每隔四个数据点显示一个标记
hold on;
plot(x,y7,'-d','MarkerIndices',1:5:length(y7));%创建一个线图并每隔四个数据点显示一个标记
hold on;
plot(x,y8,'-^','MarkerIndices',1:5:length(y8));%创建一个线图并每隔四个数据点显示一个标记
hold on;
plot(x,y9,'-v','MarkerIndices',1:5:length(y9));%创建一个线图并每隔四个数据点显示一个标记
hold on;
plot(x,y10,'->','MarkerIndices',1:5:length(y10));%创建一个线图并每隔四个数据点显示一个标记
hold on;
plot(x,y11,'-<','MarkerIndices',1:5:length(y11));%创建一个线图并每隔四个数据点显示一个标记
hold on;
plot(x,y12,'-p','MarkerIndices',1:5:length(y12));%创建一个线图并每隔四个数据点显示一个标记
hold on;
plot(x,y13,'-h','MarkerIndices',1:5:length(y13));%创建一个线图并每隔四个数据点显示一个标记
hold on;
