We have just released a first public beta of our new product – amCharts Quick Charts for WPF & Silverlight. It’s a free and open source charting control set for both Silverlight and WPF.
Quick Charts motto is: Ease of Use, Speed, Small Footprint. It is amCharts Bundle's little brother. It has less features, but concentrates on what's important for the majority of users. In order to achieve this we didn't just strip the features off of amCharts Bundle, but created Quick Charts from scratch.
Current release supports line and column charts only. Support for other chart types coming soon.
