Problem creating graph with gnuplot with time on x-axis

Let me start by saying I'm new to gnuplot and not very good at unix at all..

Anyway, I'm each minute measuring temperature and humidity and saves the last 60 readings along with time in a textfile, values_minute.

The contents of the file is formatted like this: time temperature humidity

Code:

14:10 22.8 19.1
14:11 22.8 19.1
14:12 22.8 19.1
14:13 22.8 19.0
14:14 22.8 19.0
14:15 22.8 19.0
14:16 22.8 19.0
etc...

I'm trying to create a graph using gnuplot, working with the shell first. Later I will do it with a script that will run once a minute to generate a "realtime" graph to be publish on a web site.

Code:

gnuplot
set terminal png
set output "graph_realtime.png"
set yrange [10:50]
plot "./values_minute" using 1:2 title 'Temperature' with lines; \
"./values_minute" using 1:3 title 'Humidity' with lines

But I'm given the error "invalid command". I'm quite frankly lost.
