How to include any view into the same panel
If you can use a PHP snippet in your panel you could use views_embed_view($name, $display_id = 'default') to render the view from url.

Let's suppose your panel's url is /mypanel. You can use /mypanel/myviewsname/displayname to access that panel with a particular view and display using the following code in a PHP snippet:

&lt;?php
$display = arg(2)?arg(2):"default";
print views_embed_view(arg(1), $display);
?&gt;


arg() gets a list of arguments passed through url. views_embed_view() embed a view in a PHP snippet and it will return nothing if no adequate view name is passed. This should work whenever myveiwsname is an actual view name and displayname is an actual display of that view or is not provided.

You may be able to include PHP in a panel only if you have PHP filter module installed.

You should use PHP filter module with caution.
