幀數的概念

我們通常說幀數，簡單地說，就是在1秒鐘時間里傳輸的圖片的幀數，也可以理解為圖形處理器每秒鐘能夠刷新幾次，通常用fps（Frames Per Second）表示。

每一幀都是靜止的圖象，快速連續地顯示幀便形成了運動的假象。高的幀率可以得到更流暢、更逼真的動畫。每秒鐘幀數 (fps) 愈多，所顯示的動作就會愈流暢。

private Steema.TeeChart.TChart tChart;

tChart = new Steema.TeeChart.TChart();

Graphics3DDirect2D D2D = new Graphics3DDirect2D(tChart.Chart);

tChart.Graphics3D = D2D;//Graphics3D屬性

tChart.Graphics3D.BufferStyle = BufferStyle.None; ?//此處無需打開雙緩沖,僅GD+的時候需要打開

If you require a feature that we haven't added to the standard TeeChart properties and methods then, with almost unlimited flexibility, you can add it yourself using the TeeChart Custom draw Canvas methods.

Custom draw permits you to output your own objects and text to the Chart panel associating them with runtime variables and Chart conditions.

These could take the form of hints on passing a mouse over a data Series object or a message triggered by a threshold exceeded. The Custom Canvas also supports a variety of 3D objects.?

These objects are available from the instances of the Graphics3D class passed to events such as the AfterDraw event.

For more information on drawing to the TeeChart Canvas please see "Tutorial 13 - Custom drawing on the Chart Panel" .
