Để vẽ 1 đường x theo t và một đường y theo t, chúng ta sử dụng cú pháp :

plot([xmin xmax ymin ymax])

axis([xmax xmin ymax ymin])

axis([ymin ymax xmin xmax])

y=[150 300 150 300];bar(y)

y=[150 150 300 300];pie(y)

y=[150 300 150 300];pie(y)

plot(p,q,i)

subplot(i, p,q)

plot(i, p,q)

pie(1,2,3,{'I1','I2','I3'})

pie(1:3,{'I1','I3','I2'})

pie(1-3,{'I1','I2','I3'})

x=[2000 4000 4000]; pie(x,3)

x=[2000 4000 4000]; bar(x)

x=[2000 4000 4000]; plot(x[3])

x = -6:0.5:6;bar(x,2*x)

x = -5:0.5:5;bar(x,x)

x = -6:0.5:6;bar(x,-2*x)

t=0:0.1:1;plot(t);hold on

t=0:0.1:1;plot(t);grid off

t=0:0.1:1;plot(t);clear

subplot(2,1,2); subplot(2,1,2); x=[2 4 8]; plot(x)

subplot(1,2,2); subplot(1,2,2); x=[2 4 8]; plot(x)

subplot(1,2,1); subplot(1,2,2); x=[2 4 8]; plot(x)

x = [1 4 3 2];explode = [0 1 0 1 ];pie(x,explode)

x = [1 2 3 4];explode = [0 0 1 1 ];pie(x,explode)

x = [1 2 3 4];explode = [1 1 0 0 ];pie(x,explode)

plot(x, y)

bar (x,y)

pen(x,y)

plot(function,limits)

bar(function,limits)

pie(function,limits)

xlabel ('DIEN AP AC')

ylabel ('DIEN AP AC')

plot('DIEN AP AC')
