Hi
I'm working on monitoring system that shows energy consumption.
On the other hand, I need to get reports.

I've wanted to use Chart Control on C# Framework 3.5 Windows Form.
The program will get the data from db and will show on chart by the way, but actually it's hard to find samples and also it will be my first chart drawing..

So do you have any suggestions or samples?

thanks.
