Line Options

This dialog allows modification of lines or arroww which have been created with either the Draw Arrow command from the Graph Menu or the Ctrl-Alt-A. The dialog can also be opened by double clicking on an arrow or line, or by right clicking a selected arrow or line and then selecting Properties... from the resulting pop-up menu.

The first tab of the dialog allows changing the color, line type and line width. Line width is set in pixels. It is possible to define a default style for all new lines by clicking the Set Default button.

The Arrow Head tab is used to modify arrow head shape. Length is in pixels and the angle is in degrees. It is also possible to define a default style for arrow heads using the Set Default button.

The Geometry tab is used to specify the starting and ending points of the selected line/arrow. The coordinates can be set as a function of the scale values displayed on the left (Y) and bottom (X) axes, or in pixels, by choosing the desired method from the Unit pull-down list. Pixel coordinates are relative to the top-left corner of the layer which contains the line.
