How to plot a horizontal line?

My function is just y=2050 and I need to plot it w/o using "yline", because it's not a graph, actually. I just type this:

x=[0:0.1:110];
y=[0:10:2060];
g=2050;
plot(x,g)

And I don't get anything. Like, completely anything:

And also after that I need to mark a point (100,2050) and be able to make it bigger than my graph.

How do I solve these problems?

Great thanks to drummer and darova! I finally have the graph I wanted. Final code:

x=[0:0.1:110];
y=[0:10:2060];
g=2050;
p1=plot(x,g+x*0,"g");
p1.LineWidth=2;
hold on
p2=plot(100,2050,"r*");
p2.LineWidth=15;
xlim([1 110])

Result:

Try this

[Mikhail Konovalov]

Can't see it clear enough. Could you write it with printed text, please?

[darova]

plot(x,g+x*0)

[Mikhail Konovalov]

Thank you, it looks very nice. How do I mark a point in this graph, though?

[darova]

Can you make a simple sketch of the result you expect?

[Mikhail Konovalov]

I've already got the result I wanted. Thank you!

[drummer]

y = 0:0.1:110;
x = 2050.* ones(length(y));
plot(y,x)
xlim([1 110])

[Mikhail Konovalov]

Looks nice! And how do I set a point at (100;2050)?
