Plot vectors in matlab as a straight line

I have the following two vectors:

1. vector r (1*300000) . This vector has the following values:

    All indices from 1 to 122001 have values 2000
    All indices from 122002 to 202001 have values 7000
    All indices from 202001 to 300000 have values 1200

2. vector T (1*300000). This vector has values starting from 0, and consecutive values increment by 0.000001.

My goal is to plot r vs T. There should be a 3 straight lines in the figure (2 jumps, where value of r changes from 2000 to 7000 and other where value of r changes from 7000 to 1200).

I appreciate any help.

Thanks.

plot(T(1:122001), r(1:122001), T(122002:202001), r(122002:202001), T(202002:end), r(202002:end))

Hey Walter, that's giving me the exact output which I wanted. Thankyou soo much

 plot(T, r)

Hey Thorsten, I tried that before posting the question. That's not giving me 3 different continuous lines.

So what do you see when you use this command?
