Making graphs in excel.

[Delta6326]

I'm trying to teach my self how to make graphs in excel. i think im starting to get the hang of it.

I was wandering if any one knew how to make the words on the left side go vertical instead of horizontal.

Here's my Graph :) http://img.techpowerup.org/100223/Capture0063.jpg and http://img.techpowerup.org/100223/Capture0065.jpg

Here's the graph i used as a reference

Any ideas on how to make my graph's cooler looking?
