# 平滑線屬性

您可以在顯示線條的圖表中 (線條型或 XY 型)，選擇顯示曲線，而不是直線。有一些選項可控制這些曲線的屬性。

若要使用此指令...

In the Chart Type dialog of a Line chart or XY chart that displays lines, choose Stepped in the Lines type drop-down, then click the Properties button.

Press Shift+F1 and point to a control to learn more about that control.

## 變更線條屬性

1. 選取立方形齒條或 B 齒條。

   These are mathematical models that influence the display of the curves. The curves are created by joining together segments of polynomials.

2. 或是設定解析度。較高的值會得到較平滑的線條。

3. For B-spline lines optionally set the degree of the polynomials.
