在进行数据比较或者演示时，一个形象的图表不但非常直观，而且也很生动。本实例介绍如何在Delphi中设计形象的三维饼图。 　　向窗体上添加一个TVtChart组件和一个TTimer组件，其中TVtChart组件用于显示饼图，而TTimer组件用于不停地改变饼图的数据，获得动态的效果 -In the comparison of data or presentation, a chart image is not only very intuitive, but also very lively. Examples of how the introduction of the Delphi to design the image of three-dimensional pie chart. To add a TVtChart form components and a TTimer components, including components used to display TVtChart pie, and TTimer components continuously change the pie chart for the data, access to dynamic effects
