Good Silverlight 4.0 chart / graph component? [closed]

Question

I've been using the Silverlight Toolkit but I'm finding the quality lacking; in particular this memory leak / phantom point bug renders the Chart component completely unusable.

Can anyone recommend a good chart / graph component for Silverlight 4.0? I'm looking for one that provides:

• multiple simultaneous series, both scatter and line
• multi-select of points
• configurable tool-tips
• automatic axis scaling
• real-time update of data

That last point sounds trivial but is tripping up the Silverlight Toolkit Chart; if you rapidly change the axis range, it sometimes leaves phantom points behind in addition to the points it should be displaying.

Answer 1

Take a look at Visifire. It supports all the above requested features.

Answer 2

You could try Visiblox.

Answer 3

You could take a look at the Data Visualization suite offered by Infragistics. I'm not really a big fan of Infragistics but I have been impressed with some of their charting components.
