## regression-line-colors

Arguments: plot-view

Returns the regression-line-colors property of a `plot-view` object, which is associated with a `plot-widget` control. The value may be set at creation time by passing the :regression-line-colors initarg to make-instance, or any time later by calling (setf regression-line-colors).

This is a list of colors for regression lines for the multiple chart-objects of the `plot-widget`. The first element of the list is the color to use for the first chart object, and so on, cycling back through the list as needed.

Each value in the list should be either an RGB color object (see make-rgb) or a constant symbol or global variable whose value is an RGB. The default value is a list of the color variables `blue`, `dark-green`, `red`, `dark-magenta`, `dark-cyan`, `gray`, `black`, and `dark-yellow`.

The regression lines are drawn only if the draw-regression-lines property of the plot-view is true.
