microsoft chart control OR wpf toolkit?
===

To be more specific I would like to rephrase my prevous question http://stackoverflow.com/questions/11542214/should-i-use-microsoft-chart-controls-your-suggestions-please

I need to draw charts, zoom, scroll, add annotations (I plan to add labels to indicate "trades" on chart of price of some stock)

Which one more powerfull easy and suitable? What are prons and cons of each other?
