I have a general question.  Is there a setting that can be used for a
multiple line type?  The situation is that I want a solid line between x
and y points but if the y point is missing, I want a dashed line type to
the next point.  In other words, if point 1 to 2 exists, make that line
solid, otherwise, make it dashed up to the next existing x/y point.

Additionally, what plot type would you recommend for a plot with two Y
points per X?  The two points would be joined by a vertical line.  The
average of the two is the dual type line described above.
