Lines are simple drawing elements which can be added to a worksheet. Figure 9-20 shows a wide orange line element placed above the worksheet grid.
The properties of the line can be altered with the Properties menu item in the context menu which appears when the mouse cursor is placed over the line and one of the secondary mouse buttons is pressed.
Lines have two properties, the color used for the line and the width of the line.
The color of the line can be altered by moving the mouse pointer over the button with the icon of a small, black, downward pointing arrow and then clicking with the primary mouse button. This will open up a panel with a number of standard colors presented as small squares. Any of these colors can be selected by moving the mouse pointer over the desired color and pressing once with the primary mouse button. Alternatively, a custom color can be chosen by clicking on the button at the bottom of the panel. This will open up the color chooser dialog. In this dialog colors can be defined using the numeric boxes or can be selected using the color triangle. The color can be selected by Clicking on the outer circle while the darkness or lightness can be selected by clicking inside the triangle. Once the desired color has been configured, this color can be used for the label outline by clicking on the OK button.
The line width can be changed either by typing a new number into the text box or by using the up and down arrows to increment or decrement the width number.
