That scripts seems to be corrupted. Following lines make little sense:

> set ytics 1.000, 1.000
Why set ytics, when you change them again in the next line?

> set ytics("MET:1" 1.000,"TYR:2

Where is the closing bracket? I guess there is half a line missing.

> set cbtics 0.000 7.000 1.0

Interval zero makes no sense, although you can give any amount of
numbers here, the one actually used is the last one. That's a small
parser bug imo. You should give only one number here, and it must be
>0. (See "help xtics")

Also you have a second line with "set cbtics" further down, so you
can just delete this one.

You only give two lines of data, that's not enough to actually plot
anything.
