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.

We’ve used a different licensing scheme for our WPF & Silverlight charts than for other products. According to feedback from several prospective customers, this created a lot of confusion. So, by popular demand, we’ve decided to unify licensing scheme across all products.

From now on in addition to free linkware license these license types are available for amCharts WPF & Silverlight products:

• Single application license – for use in a single non-redistributable application or web site you’ve developed for yourself or your client;
• Multiple applications license – for use in multiple non-redistributable applications or web sites you’ve developed for yourself or your clients;
• Developer (OEM) license – for use in redistributable applications. Includes access to source code.

Previous licenses will be honored for as long as they are valid and upgrade options for future major version updates will be offered.

Don’t forget that you can still get Stock Chart licenses with 30% discount. The offer expires really soon (within 1-2 weeks).

If you have any questions about this licensing change, licensing in general or any other non-technical inquiries about our WPF & Silverlight products, feel free to contact us at net@amcharts.com.
