Comment by user: Block on profile page

I am using views 2. I tried doing a lot of things. I created a block and it is set on the profile page. What should I edit in views so I can let others see the comments posted by the user on the profile?

Currently it is showing all the comments of the website.

$view = new view;
$view->name = 'recent_comments_by';
$view->description = '';
$view->tag = '';
$view->view_php = '';
$view->base_table = 'comments';
$view->is_cacheable = FALSE;
$view->api_version = 2;
$view->disabled = FALSE; /* Edit this to true to make a default view disabled initially */
$handler = $view->new_display('default', 'Defaults', 'default');
$handler->override_option('relationships', array(
  'uid' => array(
    'label' => 'User',
    'required' => 1,
    'id' => 'uid',
    'table' => 'comments',
    'field' => 'uid',
    'relationship' => 'none',
  ),
));
$handler->override_option('fields', array(
  'subject' => array(
