In this case you want to call an extension from another extension, you can call renderTimeline() from your code.
Thanks. I'll be reading the article on the link you provided. And I'll try asap how to make graphs. For now, I'm resolving if how could i get the category name of an article. I used an extension yet it just create an article to a category. I used the getContent() method and checks for the [[Category:Name]] in the text. I'm still debugging for on some rows the category name couldn't be displayed...
