## draw-regression-lines

Arguments: plot-view

Returns the draw-regression-lines 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 :draw-regression-lines initarg to make-instance, or any time later by calling (setf draw-regression-lines).

This is a boolean value (`nil` or true) indicating whether to draw a regression line for each of the chart-objects of the `plot-widget`. When drawn, each regression line will be a straight line segment that minimizes the sum of the squares of vertical distances between the plotted points for one chart object and the regression line itself. The default value is `nil`, and so no regression lines are drawn by default.

The line styles that are used to draw the regression lines may be specified with the regression-line-colors, regression-line-dashings, and regression-line-widths properties.
