	)			`[static, private]`

Draws the line segments with line style.

When there are multiple data points at the same x pixel coordinate, it is inefficient to simply draw vertical lines connecting them by overlaying. Instead, only a single vertical line representing the overlaid multiple vertical lines is drawn at that x pixel coordinate.

That's why vertical line is handled differently from non-vertical line in this method.

Parameters:

	gc	the graphic context
	xAxis	the x axis
	yAxis	the y axis
	xseries	the x series
	yseries	the y series
	isHorizontal	true if orientation is horizontal
