How do I make my form scrollable in Android?

I am new to android. I have drawn a pie chart, and when I see 开发者_运维知识库it vertically, it's okay. When I change the view to horizontal, I just get the first half of the chart. I want to be able to scroll down. How do I implement this?

Use ScrollView. http://developer.android.com/reference/android/widget/ScrollView.html
