Visifire 是一个基于SilverLight的 Chart组件，VISIFire 公司提供了 Open Source 的 Silverlight 2 Chart 组件，遵循GPL v3，可以在 ASP, ASP.Net, PHP, JSP, CodeFusion, Ruby on Rails 以及 HTML 中使用。支持的Chart类型挺多的（支持饼图，柱状图，圈图，区图等等）。
- In Line, StepLine and Spline charts, markers were disappearing while zooming and updating DataPoints simultaneously at realtime.
- If the FontSize of AxisLabels for Secondary AxisY was set to an odd value, AxisLabels were clipping.
- In Polar chart if any DataPoint’s YValue was set to NaN, it was considered as zero internally.
- Opacity property was not working as expected for DataSeries and DataPoint if set through property binding.
- If there was single DataPoint in chart and YValue property for that DataPoint was set to a decimal value, AxisMaximum was not getting generated properly.
