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 \<emph\>Format - Line\</emph\>.
