Today I found this link which explain how to upgrade GNUPLOT 4.2 which default on Ubuntu Lucid become GNUPLOT 4.4. GNUPLOT is the open source software that can be used for plotting figure, chart, etc. I work with it since my wife introduced it last year.

Here is the steps written on that link:

wget http://ftp.us.debian.org/debian/pool/main/g/gnuplot/gnuplot-nox_4.4.0-1.1+b1_i386.deb
wget http://ftp.us.debian.org/debian/pool/main/g/gnuplot/gnuplot-doc_4.4.0-1.1_all.deb
wget http://ftp.us.debian.org/debian/pool/main/g/gnuplot/gnuplot-x11_4.4.0-1.1+b1_i386.deb
wget http://ftp.us.debian.org/debian/pool/main/g/gnuplot/gnuplot_4.4.0-1.1_all.deb
sudo dpkg -i gnuplot*

 

I hope, this information will useful, at least for myself.
