Creating Catagories that Appear on Columns

Hello,

Would there be a way to make it so that the column on a page shows only a specific type of post category?

So that, if I were to have two different categories posting two different things, updated links would appear on two different columns?

I know the code somehow uses this function:
<?php get_archives(‘postbypost’, 3); ?>

Im just not sure how to link it properly to the category.

Thank you!
