Arguments: line-drawing-view

Returns the value of the line-colors property of a line-drawing-view. The value may be set at creation time by passing the line-colors initarg, or any time later by calling (setf line-colors).

The colors that are used to draw the graph lines on a line-drawing-view in a chart-or-plot. The value should be a sequence (list or vector) of RGB objects (see make-rgb) and/or symbols that are globally bound to RGB objects. The default value is a list returned by the following (see make-rgb for a list of all pre-defined colors):

(list 'blue 'dark-green 'red 'dark-magenta 'dark-cyan
      'gray 'black 'dark-yellow)

If the value is nil, then all lines are drawn in black. Otherwise, the first object in the chart-widget's sequence of chart-objects is drawn with the first color, the second object with the second color, and so on. If there are fewer colors in the list than there are chart-objects, then the drawing code will cycle back through the list of colors as needed.

The line-colors are also used to draw the non-pixmap icon-images of the line-drawing-view when the icons-filled property is a value other than t. This property is otherwise used only when the draw-lines property is true.

See plot-widget, chart-widget and also cg-chart-widget.htm.
