Weather Graph in PHP

A while back I showed you how I collect weather throughout the day for several cities of my choosing, well-collecting data is only good if you can use it or do something with it so I now started playing with GD module for PHP.
While not totally impressive I do like the possibilities so here goes a couple of screenshot from what I’ve done

Today’s local temperature changing throughout the day!
Temperature interval across 31 days period.

So as long as I know what I want to see and how to run the MySQL query I can generate those graphs.

I shall continue tinkering with different languages and code as long as I am having fun! 🙂
