Features
　

• Small footprint assemblies provide simple deployment as well as a rich design-time experience.
  Pocket Chart FX for .NET provides a design-time experience assembly compiled against the .NET Framework that integrates seamlessly in Visual Studio .NET, allowing you to setup chart attributes and properties easily. This consistency ensures that there are no features in the design time version of the control that will not be available in the run-time version limited to work in the .NET Compact Framework and both assemblies adhere to the “small is good” principle for mobile applications.
  
  
  　
  • Getting Help & Sample Code: The Chart FX Resource Center not only provides specific samples for Pocket Chart FX for .NET but has been also provisioned with the .NET Compact Framework emulators so you can see each sample running in a virtual Pocket PC environment. To activate, simply select the Smart Devices radio button at the top of the Resource Center. The picture to the left depicts a live Pocket Chart FX for .NET sample in the Resource Center.
    　
  • Additionally the Chart FX Resource Center features an API Section where all Chart FX methods and properties can be accessed. Please be aware that those objects, properties and methods supported in the .NET Compact Framework will be accompanied by the “Supported by the Pocket Chart FX for .NET”.
    　
• Adherence to .NET Compact Framework design guidelines (runs 100% natively in Pocket PCs).
  As a GDI+ intensive component, Chart FX has been developed with coding practices that can help improve draw speeds when using Graphics draw calls. This is particularly important when considering applications in a mobile platform where memory, CPU speed, and other resources are at a premium. Considering that a PocketPC screen resolution is 240x320, we made sure chart elements that usually take a lot screen space were removed from the default chart settings and that charts accommodate and display well in a “portrait” rather than a “landscape” orientation; even the Chart FX default color palette has been changed to improve end users ability to read charts in small Pocket PC screens.
  
  　
• Support for other mobile related technologies and tools like SQL Server CE and Pocket Access.
  SQL Server CE extends Microsoft SQL Server to Microsoft Windows CE-based mobile devices, while providing developers with a consistent programming model for rapid application development. Chart FX can read from native SqlCEConnections and SqlCEDataAdapters for easy chart population. The following C# code demonstrates how easy it is to populate a chart from SQL Server CE data source.
  
  SqlCeConnection myConn = new SqlCeConnection(@"Data Source = \Test.sdf");
  myConn.Open();
  SqlCeCommand myCommand = new SqlCeCommand(sSql, myConn);
  SqlCeDataAdapter sqlCeAdapter = new SqlCeDataAdapter(myCommand);
  DataSet dsChart = new DataSet();
  sqlCeAdapter.Fill(dsChart);
  Chart1.DataSource = dsChart.Tables[0];
  　
• Free for development purposes to existing Chart FX for .NET or Chart FX Developer Studio users.
  If you are an existing Chart FX for .NET or Chart FX Developer Studio owner please visit our support site or contact our sales department to obtain your free copy of Pocket Chart FX for .NET. Runtime fees may apply. For additional information visit the licensing section.
  　

产品特性：

• 小范围组装特性提供简单部署功能和丰富的设计体验
  .NET版本的袖珍图表控件FX（Pocket Chart FX for .NET）提供了设计组装体验，允许在.NET开发框架下编译，并且可以与Visual Studio .NET开发框架无缝集成；同时允许你轻松方便地设置图表的属性。它所具有的一致性可以保证：没有任何功能在设计时有效而在运行时却无效，而且不仅仅局限在.NET紧缩版框架中；两种框架下面的组装都坚持为移动应用程序考虑设计的“越小越好”的原则。
  　
• 获取帮助和示例代码:
  图表控件FX资源中心不仅提供了为.NET版本的袖珍图表控件FX所提供的具体示例代码，而且还提供了.NET紧缩版框架仿真程序，你可以在虚拟的袖珍电脑环境下看见每一个示例代码的运行情况。如果想激活运行某个示例代码，只要简单在资源中心的顶端选择“Smart Device”单选按钮即可。资源中心左边的图片将会描述活生生的代码运行情况。 图表控件FX资源中心另外一大特色就是提供了API（应用程序接口）区域，从中可以访问到所有的图表控件FX的方法和属性。要提醒的是，那些.NET紧缩版框架支持的对象，属性和方法将会有“Supported by the Pocket Chart FX for .NET”伴随说明。
  
  
  　
• 坚持.NET紧缩版框架设计指导原则（100％代码在袖珍电脑本机运行）
  作为一个图形设备接口加强的控件，图标控件FX在其开发过程中，当涉及到绘图功能时，是通过能够改善绘图速度的编码来实现的。这一点在开发移动平台的应用程序时非常重要，因为移动平台在内存，CPU速度以及其他资源都是非常宝贵的。假设袖珍电脑的屏幕分辨率是240×320，我们必须确保：占据屏幕空间的图表元素从默认的图表设置中去除；同时图表以肖像描绘的方式而不是风景拍摄的方式适应并且显示出来；甚至调整图表FX的默认调色板来改善终端用户在小小的袖珍电脑屏幕上观看图表的效果。
  　
• 支持其他的移动相关技术和工具（SQL Server CE and Pocket Access）
  SQL Server CE将Microsoft SQL Server扩展到基于Microsoft Windows CE平台的移动设备上，同时给程序开发人员提供了连续的快速应用程序编程模型。图表FX可以通过读取本地的SqlCEConnections和SqlCEDataAdapters来轻松地绘制图表。下面的C＃代码展示了从SQL Server CE 数据源绘制图表是多么方便简单。
  
  SqlCeConnection myConn = new SqlCeConnection(@"Data Source =
  \Test.sdf");
  myConn.Open();
  SqlCeCommand myCommand = new SqlCeCommand(sSql, myConn);
  SqlCeDataAdapter sqlCeAdapter = new SqlCeDataAdapter(myCommand);
  DataSet dsChart = new DataSet();
  sqlCeAdapter.Fill(dsChart);
  Chart1.DataSource = dsChart.Tables[0];
