我有一个 TChart 组件，带有一个 Fastline 系列和一个 ColorBand 工具。在表单上，我还有一个启动计时器的按钮。在每个计时器经过事件中，我都会生成 2048 个随机数据样本并更新 Fasline 系列。当我启动计时器时，TChart 上没有动画！不过，它似乎是随机工作的......而且，当我隐藏和显示表单（通过最小化/最大化，或通过 tChart1.Hide()/tChart1.Show()）时，动画再次开始工作，或者当我在启动计时器之前拖动其中一条 ColorBand 线，然后动画就起作用了。但是当我首先启动计时器时动画不起作用。而且，此外，当它不工作时，TChart 似乎被冻结，即，ot 不响应任何鼠标命令，例如平移或缩放。这是一些代码：
在我的 form.designer.cs 中：
partial class Form1
{
/// <summary>
/// Required designer variable.
/// </summary>
private System.ComponentModel.IContainer components = null;
/// <summary>
/// Clean up any resources being used.
/// </summary>
/// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
protected override void Dispose(bool disposing)
{
if (disposing && (components != null))
{
components.Dispose();
}
base.Dispose(disposing);
}
#region Windows Form Designer generated code
/// <summary>

/// the contents of this method with the code editor.

{

我有另一个问题。我想通过编写自定义 API（自定义用户控件）来创建 TeeChart 组件的黑盒实现以公开特定功能，以便我可以在其他项目中使用它，并且我的一个或多个同事可以在他们的项目中使用它。我应该购买什么版本/许可证的 TeeChart 可以让我将 TeeChart 功能包装在可用于各种项目/计算机的自定义组件/dll 中？
