Quick Charts is an easy to use, fast set of charting controls for WPF & Silverlight. And it’s FREE and Open Source (Ms-PL)!

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.

Key features:

• Ease of use

  By analyzing user feedback we’ve determined what features are most important to the majority of scenarios and left everything else out. As a result we have an API that is very easy to master.

• Speed

  Absence of complicated rarely used features let’s the charts do what they do fast.

• Small footprint

  Current version is only 54kb uncompressed and in compressed form it’s only 19kb! This is especially important in Silverlight where every byte counts.

• Support for essential chart types

  QuickCharts support Line, Column, Area and Pie charts.

• Automatic axes and grid

  Serial chart automatically recalculates and rearranges axes and grids based on chart size (try resizing panes in the demo above).

• Support for data-binding

  As any other bindable WPF and Silverlight controls quick charts can be bound to any data object implementing IEnumberable interface.

• Free, unbranded & Open Source

  Quick Charts are absolutely free. There’s no branding, link backs or anything like that. And source code is released under very permissive Ms-PL license.

Beta version of amCharts Quick Charts for WPF & Silverlight is available for immediate download.

• FEATURE ADDED: added Chart.Collapse() and Chart.Show() methods to hide/show individual charts in stock chart and re-layout other charts.
• BUGFIX: "’NaN’ is not a valid value for property ‘Y1′." exception was thrown at design-time.

• BUGFIX: Charts weren’t showing up in Out-of-Browser mode in Silverlight.
