Help with gnuplot to plot memory usage vs datetime stamp

I have written a shell script that looks at memory usage of a program and uses date to make a datetime stamp to a log file.

data.txt

#!/usr/bin/gnuplot
set terminal png
set output "plot.png"

set xdata time
set timefmt "%Y-%m-%d %H:%M:%S"
set format x "%H:%M"

set xlabel "time"
set ylabel "mem usage"

set title "memory use vs time"
set key reverse Left outside
set grid

set style data linespoints
plot "data.txt" using 1:3

How can I make the chart bigger and make the x-axis better so I can read it?

Well now that the data file has gotten bigger the above script doesn't work at all. I updated the data.txt in the original post in case anyone has some ideas.
