This dialog box appears when you create a text label on the coordinate plane or try to modify it's properties.

Labels are usually used to display some text information on the plot. A label is characterized by its caption, size and color, position. It may have vertical and horizontal lines.

The Text box prompts you to enter the labels caption (the text that will be displayed on the plot at a specified position). The x and y box entries must be any valid mathematical expressions. These are the coordinates of a label. The locked option locks a label so it becomes impossible to move it using a mouse.

Select Horizontal and Vertical boxes to add horizontal and vertical lines to a label.
