What must I do to display total visitor like wordpress.com

Counterize is a great stat counter for your blog – it can display total visitors, vistors today, visitors in the last 7 days and a LOT more.

1. Download the Counterize Plugin and follow the instructions:

2. Download the execPHP plugin here:

3. Place the Counterize PHP code into a PHP widget on your sidebar!

If you don’t use widgets, then insert the necessary PHP code into your sidebar.php file.

Sorry, you’ll have to ask the plugin author. You can insert code for ‘Hits from you today’, which is similar to what you want. (I think).
