Plotting a curve issue. i used to draw curves by semilogy but now i don't want it in logarithmetic form!

consider the following

a=[3/4 1/2 1/4];

bb=[4.1 3.3 2.7];

cc=[5.9 5.2 4.7];

dd=[7.9 7.6 7.3];

plot(a,bb,'red','LineWidth',2); hold on

polt(a,cc,'blue','LineWidth',2); hold on

plot(a,dd,'black','LineWidth',2); grid

how can i plot those three curves?

Slightly changing your code:

a=[3/4 1/2 1/4];
bb=[4.1 3.3 2.7];
cc=[5.9 5.2 4.7];
dd=[7.9 7.6 7.3];

figure(1)
plot(a,bb,'red','LineWidth',2); 
hold on
plot(a,cc,'blue','LineWidth',2); 
plot(a,dd,'black','LineWidth',2); 
hold off
grid

It works fine for me. Both axes are linear. Is that what you want?

yea yea it worked .. something was wrong with my matlab simulator!

thank you
