[Gnuplot-info] Some problem met while first use of gnuplot

[Pan r. <pan...@gm...>]

Hi All,

I am a newcomer of gnuplot. I used the following commands to draw a graph:

gnuplot <<'EOF'
set term jpeg
set output "hello.jpg"
plot sin(x)
EOF

But I can't see x-axis and y-axis in the output picture and the back
ground is black rather than white.
I have no idea what is matter. Could anyone please help?
