Lines section
I have created a picture that shows the mapping of properties in the lines section to the chart as shown below:
Angle lines only: If True, then house lines won't be drawn but angle lines for the ascendant, midheaven, descendant and imum-coeli will be drawn.
Angle line width: This is the width of angle lines. Usually it looks better if this is line is thicker than other house lines as it will make them stand out; especially when using whole sign house divisions.
House line style: There are multiple styles available here and the line doesn't have to be a solid line. However if the house line width is greater than 1, then it will be solid regardless of the setting here.
House line width: This is the width of the house lines which show the divisions of the houses.
Standard line width: This is the default line width for drawing wheels and is the most commonly used in the drawing routines.
