We received another forum thread from you regarding the same issue. I am pasting the answer here as well.
"We have an online sample demo showing how the chart can handle real-life scenarios. It is very similar to yours and I suggest you to use it as a reference. The demo is for Silverlight but the approach for WPF is the same. You can also view its source code by downloading the WPF Demos from your account."
I would suggest to keep the conversation in a single thread so it is easier for both sides to follow.
