Arguments: bar-chart-view

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

The colors that are used to fill the interior of the bars of a bar-chart-view in a chart-widget. 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 (the symbols name pre-defined colors, see make-rgb):

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

If the value is nil, then the bars are not filled and will be transparent. 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.

This property and other bar-chart-view properties are used only when the chart-view property of the chart-widget is :bar to display the bar-chart-view.
