Here is a first simple shot for you to get your teeth into.
I have created a class that sets up very basic charts, and a demo of same. When you have got this clear in your head we can talk about adding extra properties.
The one thing to note at this juncture is how I use the chart type enumerated list as my data type for defining the chart. This means that when you go to set the charttype, you get intellisense, which is a big bonus IMO (you know that I love enumerated lists).
