I want to plot a graph like this in Matlab

How we can do this ?

[Geoff Hayes]

@Vartika Agarwal - do you have the data needed to plot this graph? If so, what have you tried to do so far?

[Vartika Agarwal]

I want a rough idea about how we can plot such type of graph

[Vartika Agarwal]

Can you please help me?

[Geoff Hayes]

See plot for details on how to do a basic plot like in the graph. You will need some data though...is that something you can simulate?

[Geoff Hayes]

@Vartika Agarwal's answer moved her

I have the data for simulating the graph

See the following attachment and help me how i can do this ?

[Geoff Hayes]

@Vartika Agarwal - to be clear, the "data" you have is just the attached picture?

[Vartika Agarwal]

X= [73,77,81,85,89,93,100]
y= [1,2,3]
Network drop at 81 and after 85 network will work continuously.

I hope you understand my point and your help will be really appreciated.
