Real-time WPF chart .Net 4

Question

I'm working on a diagnostic tool and receives data every 25 ms. I need this data to be drawn in my chart using a lineSeries. I'm using a a wpf chart with a lineSeries which I bind in xaml to an ObservebleCollection.

The problem is that I need the collection needs to contain atleast 1600 datapoints before starting to remove them at the front.

I understand that 25 ms is a short tiem then it comes to drawing in wpf. Dose anyone have any solution to my problem?

Regards

You should check out SciChart, which can handle data updates at 1ms. It renders like a game-loop, so only draws when new data is appended and the UI thread is free. Some more information at www.scichart.com/wpf-chart-features which shows the features and talks about performance.

Disclosure: It's my own component, so ask any questions if you have them!
