This little snippet adds subtitle to jfreechart.

JfreeChart chart = ChartFactory.createBarChart("Title Goes Here",....);
 
chart.getTitle().setFont(new Font("Tahoma", Font.BOLD, 20));
TextTitle dataTitle= new TextTitle("This is subtitle");
dataTitle.setHorizontalAlignment(HorizontalAlignment.CENTER);
dataTitle.setFont(new Font("Verdana", Font.ITALIC, 18));
chart.addSubtitle(dataTitle);

Install Perl modules without root access

Umakanthan — Thu, 17 Jun 2010 11:38:14 +0000

Sometimes we need to install perl modules on a machine where you dont have root (sudo) access. Here are the steps to install perl modules as a normal user

Get Source package from search.cpan.org ( Example -> http://search.cpan.org/~pythian/DBD-Oracle-1.24b/Oracle.pm)
Extract the content into your local directory.
Navigate to the extracted directory ( Ex- cd /home/ukanth/oracle )
Now compile the source using the following command

perl Makefile.PL PREFIX=/home/ukanth/oracle-perl-module

This will override the default installation directory.
Then,

make

and

make install

If you don’t find any error in the installation, you are now ready to use it in your perl program.

use lib '/home/ukanth/oracle-perl-module/lib/site_perl/5.8.3/i686-linux-thread-multi'

This is very simple way to install perl modules to custom directory( where you have read/write access ) .
