Editing Curves
A curved line segment consists of two data points (endpoints) and two control points (handles). A control line connects a control point to a data point. You can change the shape of a curve by converting a data point to a different type, or by dragging the control points to a different location.
You can also modify the properties of the line by selecting the line and choosing Format - Line.

- Do one of the following:
- Drag a data point to resize the line. If a control point overlies the data point, drag the control point until you can see the data point, and then drag the data point.
