Can Anyone let me know what all events are supported by Teechart and also can we detect the data or property edited by user in the editing windows.
Thanks Akshay

注意 TeeChart ActiveX 是 TeeChart VCL 版本的包装器。
我们可以在编辑窗口中检测到用户编辑的数据或属性吗
一般不会。当然，您可以在打开编辑器之前保存某个属性的状态，以便稍后进行比较。
另一方面，请注意 TeeChart 编辑器被认为可以帮助开发人员设计他们的图表，从而最大限度地减少代码编写，但并未考虑到最终用户。它有很多选项，很难预测和处理用户可能设置的所有可能性，其中一些不一定是连贯的。
