speeding up wpf datavisualization charts

WPF 4 DataVisualization charts are reasonably quick. Microsoft have optimized them over the years. We have a commercial component elsewhere in our company ChartFX , but this cheap and cheerful version seems to suit our needs, which includes refreshing every second or so.

We had  a few hiccups. We came across a strange bug, where the chart data with the same key in a charted key value pair wasn’t really refreshing correctly. It kept adding new data items with the same key. The C# key value pairs didn’t bind correctly. Once we wrapped these things in an object, the binding just worked.

Here are a couple of potentially useful links with general info, if you still feel the need for more speed:
