Linestyle does not change

Hi, am having a trboule with plot and linestyle commands.

Am using the following code

plot(t,r2,'--b');hold on
plot(t,r3,'-.r'); hold on
plot(t,r1,':g'); hold off

But still am having the same linestyle on all curves (--)?

I have tried several ways to go around this problem, but with no luck at all

Thanks

Which release are you using, and which operating system? Could you show us

get(gcf, 'renderer')
opengl info

It works fine for me, though the green line especially, and all the lines that I have are a lot more faint and thinner than yours.

Are you sure your r are all 1-D vectors and not 2-D matrices?

[ALZ]

Well, in fact Rs as well as Ts are all one column vector of different lengths

Answer 1

[Azzi Abdelmalek]

Increase the line width

t=0:0.1:10
r1=sin(t)
r2=2*cos(t)
r3=t
plot(t,r2,'--b');hold on
plot(t,r3,'-.r','linewidth',3); hold on
plot(t,r1,':g','linewidth',3);

Answer 2

[ALZ]

It seems the linewidth command partially solves the problem, Thank you Azzi, but increasing the linewidth is not an option, this way am going to miss some information.

Answer 3

[ALZ]

Thanks for everyone, it is a rendering problem, if anyone is interested, the problem should be solved by setting the renderer;

figure(1)
plot(t,r2,'--b');hold on
plot(t,r3,'-.r'); hold on
plot(t,r1,':g');
set(figure(1),'Renderer','painters')
